A ball is thrown vertically upward with speed 10 m//s and it returns to the ground with speed 8 m//s . A constant air resistance acts. The minimum height attained by the ball is

(a) A ball is thrown vertically upward with speed 10 m//s and it returns to the ground with speed 8 m//s . Find the maximum height attained by the ball. (b) A ball is thrown vertically upward and if air resistance is half of weight of the ball, find the ratio of time of ascent and time of descent. (C) Two balls A and B (m_(A) = 2 m_(B) = 2 m) are thrown vertically upward. If air resistance is mg//2 , find ratio of maximum height attained by them.

A ball is thrown vertically upwards with a velocity of 10 ms^(-1) . It returns to the ground with a velocity of 9 ms^(-1) . If g=9.8 ms^(-2) , then the maximum height attained by the ball is nearly (assume air resistance to be uniform)

A ball is thrown vertically upwards with a velocity of 10 ms^(-1) . It returns to the ground with a velocity of 9 ms^(-1) . If g=9.8 ms^(-2) , then the maximum height attained by the ball is nearly (assume air resistance to be uniform)

A ball thrown vertically upwards takes 4s to return to the ground. What is the maximum height reached.

A ball is projected vertically upward with a speed of 50 m/s. Find the maximum height.

A ball is projected vertically upward with a speed of 50 m/s. Find the time to reach the maximum height,

A ball is thrown vertically upwards with a speed of 9.8 m/s from the ground. Draw the x-t, v-t and a-t graph for its motion.

A ball is thrown vertically upward with a speed v from a height h above the ground . The time taken for the ball to hit the ground is

In the following problems the air resistance is constant (air resistance always opposes the motion). (a) A ball is thrown vertically upward. If time of ascent is t_(1) and time of descent is t_(2) , which time is greater ? (b) A ball is thrown vertically upward with speed u and on returning to the ground, its speed is v_(0) . Which speed is greater ? (c) Two balls A and B (m_(A) gt m_(B)) are thrown vertically upward with same speed. Which ball A or B (heavier or lighter) wil attain greater height ?
