16.A car accelerates from rest at constant rate for t sec and covers a distance x. The distance moved by it in next t seconds will be:

17.A ball is released from the top of a tower of height h metre. It takes T seconds to reach the ground. What is the position of the ball in T/3 seconds?

18.A balloon going upwards with a velocity of 12 m/s is at a height of 65 m from the earths surface at any instant. Exactly at this instant a packet is dropped from it. How much time will the packet take in reaching the surface of earth? (g = 10 m/second square)

19.A juggler keeps on moving four balls in the air throws the balls in regular interval of time. When one ball leaves his hand (speed = 20 m/s), the position of other balls will be: (Take g = 10 m/second square)

20.A particle is projected vertically upward in vacuum with a speed 40 m/s then velocity of particle when it reaches at maximum height 2s before, is: (Take g = 10 m/second square)
