A ball projected upwards from the foot of a tower. The ball crosses the top of the tower twice after an interval of 6s and the ball reaches the ground after 12s.The height of the tower is (g = 10m/s^2) : Average velocity of a particle moving in a straight line with constant acceleration a [...]

A juggler maintains four balls in motion, making each to them to rise a height of 20 m from his hand. What time interval should he maintain, for the proper distance between them.

Two cars start off to race with velocities 4m/s and 2m/s and travel in straight line with uniform accelerations 1m/s^2 and 2 m/s^2 respectively. If they reach the final point at the same instant, then the length of the path is. then the length of the path is. Two cars start off to race with [...]

Two particles are released from the same height at an interval of 1s. How long after the first particle begins to fall will the two particles be 10m apart? (g=10m/s^2) Two particles are released from the same height at an interval of 1s. How long after the first particle begins to fall will the two [...]
