A ball is released from the top of a tower of height h meters. It takes T second to reach the ground. What is the position of the ball in T/3 second - |
Answer» "" ❤️ Answer ❤️""the acceleration of the ball will be g. Initial velocity will be 0. by applying equations of motion we get s= ut+ (1/2)gT 2 h= (1/2)gT 2 ------[1] in T/3 sec
h 1 (1/2)gT 2 = (1/2)g( 3 T ) 2 (1/2)g( 9 T2 ) -------[2] from [1]and[2]we get h 1 9 h distance from point of release. therefore distance from ground is h− 9 h = 9 8h ☺️ Always KEEP smiling ☺️✌️ |

@ Moderators ⭐@ star ⭐⭐⭐✨@ Best Users.. please answer this question in 2 minplease |
|
Answer» Given: • Train travels DISTANCED with speed (V1) = 60m/h . Another distance Travelled by train = 2d with speed (v2) = 80m/h To Find : • Average speed Formula Used: •Average Speed = total distance / total time Solution : ★ Total Time (T) ➡t=s/v t1=d/60 t2=2d/80 → t2=d/40 →T=t1+t2 → Td/60+ d/40 ➡T=d/60 +d/40 t= 40d + 60d / 60 × 40 →T=d 24 Average Speed = total distance / total time → d+2d _______ d _______ 24 3d × 24 /d => Vay =72m/h Answer: Average speed of train is 72 m/h here's the answer hope it HELPS you |

Two forces with magnitudes of 20pounds and 14 pounds and an angle of55° between them are applied to anobject. Find the magnitude of theresultant vector to the nearest wholenumber? pls, solve this for me:( |
|
Answer» Answer: Here's one way to simply find the MAGNITUDE of the resultant force- finding the angle of the resultant involves additional STEPS. If you need that as well, draw a parallelogram and use the Law of Cosines. If you imagine a box being pulled buy the forces and assume 14# VECTOR is pulling horizontally, the component form for it would be: 14i + 0j From the same location that the14# force is pulling from, the 20# vector is also pulling but at a 55 degree angle higher. In component form, the 20# vector would be: 20 COS 55 i + 20 sin 55 j Using vector addition, the resultant vector would be: (14 + 20cos55) i + (0 + 20SIN 55) j = 24.47 i + 16.38 j The magnitude of the resultant vector: r= sqrt( 24.47^2 + 16.38^2) = 29 pounds |

If the distance between two equilibrium objects is halved, what will be the change of the active ball between the two objects? |
|
Answer» Answer: Gravitational FORCE between two objects VARIES directly as their masses and inversely as the square of the distance between them. So, when the masses of both objects are HALVED without CHANGING the distance, the gravitational force between them would become one-fourth of the original value... |
