A body of mass 2 kg is at rest 500 joule work is done on the body to raise it to 10 meters what is the speed |
|
Answer» _______________________ ★ Gɪᴠᴇɴ :-
__________________________★ Tᴏ Fɪɴᴅ :-
__________________________★ Sᴏʟᴜᴛɪᴏɴ :-To FIND , speed of the body firstly we NEED to find force ACTING on the body & acceleration acted . As we know that , W = F × S Where,
Substituting the values we have, ➠ 500 = F × 10 ➠ 500 ÷ 10 = F ➠ Force = 50 NF = m × a ➠ 50 = 2 × a ➠ 50/2 = a ➠ acceleration = 25 m/s² ________________________ Now , finding speed of the body Using , v² = u² + 2( aₙₑₜ )S Where,
Note :- Here , the initial velocity ( u ) will be 0 m/s , because the body is STARTING from rest. ➥ v² = 0² + 2(25)(10) ➥ v² = 500 ➥ v = √500 ➥ v = 10√5 m/s Hence , speed of the body is 10√2 m/s __________________________ |

A bus starting from rest moves with a uniform acceleration of 0.1 m/s for 2 minutes. Find : (i) the speed acquired, (ii) the distance travelled. |
|
Answer» Correct question:- A bus starting from REST MOVES with UNIFORM acceleration of 0.1m/s² for 2 MINUTES.Find : (i)the speed acquired (ii)the distance travelled Given:-→Initial velocity of the bus=0 →Time taken=2 minutes →Acceleration of the bus=0.1m/s²
To find:-→Speed/Velocity acquired(Final velocity) Solution:-Here,we can see that the time is given in minutes,so we shall firstly convert the time into seconds. =>1 minute=60 seconds =>2minutes=2(60) =>120 seconds By using the 1st equation of MOTION,we get:- =>v=u+at =>v=0+(0.1)120 =>v=12m/s Now,by using the 2nd equation of motion,we get:- =>s=ut+1/2at² =>s=0×120+1/2×0.1×(120)² =>s=0.05×120×120 =>s=720m Thus:- →Speed acquired by the bus is 12m/s. →The distance travelled is 720m. |
