8A paraglides jumps from an aeroplane. He falls down witha Velody of 78 m/s. He opens his parachote in air and hisVelocity of falling decreased to 50 m/s, within 12 s. Find theForce of air experienced on the paraglider if he weighs 50 kg. |
Answer» Answer
ExplanationGiven
To Find
Solution [So here we may FIRST find the acceleration of the body using the first Equation of motion, and then using the Newton's SECOND law will give us our final answer] ✭ Acceleration of the Paraglider ➝ v = u+at ➝ 50 = 78 + a×12 ➝ 50-78 = 12a ➝ -28 = 12a ➝ -28/12 = a ➝ Acceleration = -2.3 m/s² ✭ Force Experienced ➝ F = ma ➝ F = 50 × 2.3 ➝ F = 46 N |

- If length, mass and force are selected as fundamental units, what will be the dimension of time ? |
|
Answer» Answer: We are given that force F, length L, and mass M are the fundamental QUANTITIES of TIME T and hence we put, T=F x L y M
SUBSTITUTING their dimensions we have [T]=[M x L x T −2x ]L y M z
Applying principle of homogeneity of dimensions we have 1=−2x or x= 2 −1
, y= 2 1
, z= 2 1
, ∴ dimension of time becomes M 2 1
L 2 1
F 2 −1

When a ball is thrown vertically upwards, it goes through a distance of 19.6 m. Find the initial velocity of the ball and the timelaken by it to rise to the highest point. (Acceleration due to gravity,= 9.8 m/s2) |
|
Answer» When a ball is thrown vertically upwards, it goes through a distance of 19.6 m. Find the initial velocity of the ball and the time Taken by it to RISE to the highest point. (Acceleration due to gravity, = 9.8 m/s²) Here , the ball is going up against the ATTRACTION of Earth, so it's velocity is DECREASING continuosly . In other words we can say that the ball is being retarded . THUS the acceleration in the ball is negative which means that the value of g is to be used here with negative sign. Here, Now , putting all these values in the formula :- We get , Thus the velocity of the ball is 19.6 m/s which means that the ball has been thrown upwards With a velocity of 1o.6 m/s Let us now calculate the time taken by the ball to REACH the highest point. Now , the initial velocity, the final velocity and the acceleration due to gravity, so the time taken can be calculated by using the equation :
So putting the values in the above equation. we get, Thus the ball takes 2 seconds to reach the highest point of its upward journey. ______________________________ Note :-

A man sitting on a chair looks into a plane mirror that is 2.5 m away from him. He sees the image of a chart that faces the mirror and is 0.5 m behindhim. How far away from him does the image of chart appear to be?(A) 6.5 m(B) 5.5 m(C) 7.5 m(D) 3.5 m |
|
Answer» ONG>Answer: (A) 6.5 m Explanation: The plane mirror is 2.5m AWAY from him and the chart is 0.5 m far BEHIND him so the distance from the chart to the plane mirror is 2.5 m + 0.5 m = 3 m And the distance from the chart to the man in the plane mirror is 3 m + 3 m + 0.5 m = 6.5 m. We took 3 m + 3 m bcoz we are also calculating the distance of the chart in the mirror, so we doubled up the distance. Thank you :) |

A 8000 kg engine pulls a 5 wagons, each of 2000 kg, along a horizontal track. If the engine exerts a force of 40000 N and the tracks offers friction force of 5000 N, Then calculate ; (a) The Net Accelerating force and(b) The Acceleration of the Train.Warning For Spammers!☠️☠️☠️☠️☠️☠️☠️☠️☠️No Spam!Spammers Get Away!Quality Answer Needed! |
|
Answer» ong>Answer: Given : Mass of engine M=8000 kg Mass of each wagon m=2000 kg FRICTIONAL force acting in BACKWARD direction f=5000 N (a) : The net force acting on the train F ′ =F−f=40000−5000=35000 N (b) : Let the acceleration of the train be a ∴ F ′ =(5m+M)a 35000=(5×2000+8000)a ⟹a=1.944 MS −2
(c) : External force is applied directly to wagon 1 only. The net force on the last four wagons is equal to the force applied by wagon 2 by wagon 1. Let the acceleration of the wagons be a ′
35000=(5m)a ′ ⟹35000=10000×a ′
Acceleration of the wagons a ′ =3.5 ms −2
Mass of last 4 wagons m ′ =4×2000 kg ∴ Net force on last 4 wagons F 1
=8000×3.5 =28000 N Thus force on wagon 2 by wagon 1 is 28000 N. |
