A stone is falling from a mountain. The velocity of the stone is given by V = 9.8t. Draw its graph and find the velocity of the stone ‘4’ seconds after start.

A Body start from origin and move along x-axis such that velocity at any instant is given by 4t^(3)-2t is in second and velocity in m/s Find acceleration of the particle when it is at a distance of 2 m from the origin:

If the displacement of a particle is givne by s=((1)/(2)t^(2)+4sqrtt)m . Find the velocity and acceleration at t = 4 seconds.

A stone falls from rest. The total distance covered by it in the last second of its motion is equal to the distance covered by it in the first three seconds of its motion. How long does the stone remain in air?

A balloon is rising vertically up with a velocity of 29 ms^(-1) . A stone is dropped from it and it reaches the ground in 10 seconds. The height of the balloon when the stone was dropped from it is

A stone is dropped from a height of 100 m and at the same time another stone is thrown vertically upwards with velocity of 40ms^(-1) . When and where will the two stones meet ? (g=10ms^(-2))

A stone is let fall from the top of a tower 60 m high and at the same time another is projected vertically upwards with a velocity of 20 m/s. The two will meet after
