A particle is thrown vertically up with an initial velocity 9 m/s from the surface of Earth (take g – 10 m/s^2).The time (in s) taken by the particle to reach a height of 4 m from the surface second time (in seconds) is the two spheres have the same: Two spheres of same size [...]

A rocket is fired vertically from the ground with a resultant vertical acceleration of 10 m/s^2 . The fuel is finished in 1 minute, and it continues to move up. What is the maximum height reached? A rocket is fired vertically from the ground with a resultant vertical acceleration of 10 m/s^2 . The fuel [...]

A ball is dropped from the top of a building 100 m high. At the same instant another ball is thrown upwards with a velocity of 40 m/s from the bottom of the building. The two balls will meet after. A ball is dropped from the top of a building 100 m high. At the [...]

The displacement of a body is given to proportional to the cube of time elapsed. The magnitude of the acceleration of the body is proportional to The displacement of a body is given to proportional to the cube of time elapsed. The magnitude of the acceleration of the body is proportional to September 5, 2020 [...]

The displacement time graph of a particle moving along a straight line is drawn here. The accelerations of the particle during the regions OP, PQ and QR are PQ and QR are The displacement time graph of a particle moving along a straight line is drawn here. The accelerations of the particle during the regions [...]
