If the balloon was at a height of 60 m at the time of dropping the ball, how long will the ball take to reach the ground?" 2. A person standing on top of a 25m height building throws a ball upwards at a speed of 20 m/s.find the time ball will take to come down​? 3. From a tower of height H, a particle is thrown vertically upwards with a speed u. The time taken by the particle, to hit the ground, is n times that taken by it to reach the highest point of its path. The relation between H, u and n is? 4. A body is thrown vertically upwards. Which one of the following graphs correctly represent the velocity vs time? 5. A ball is thrown vertically upwards with a velocity of 20m/s from the top of a tower with a height of 25m. What is the maximum height the ball can go above the ground? 6. A particle is dropped from rest vertically from a height The time taken by it to fall through successive distances of 1 m cach will then be? 7. A ball is thrown upwards with a velocity of 100m/s. It will reach the ground after? 8. A stone is thrown upwards and it rises to a height 0f 200m. The relative velocity of the stone with respect to the earth will be maximum at ?
