Question

a ball thrown vertically up reaches a max.height 200m. if t1 and t2 are the times of ascent and descent respectively then t1:t2​

Answer 1

Answer:

a ball thrown vertically up reaches a max.height 200m. if t1 and t2 are the times of ascent and descent respectively then t1:t2​

Explanation:

A ball is thrown vertically upwards. it returns 6s later. The velocity with which it was thrown is: The time taken to reach its max height = 6/2 = 3 sec We know, T = U/g or, U = gT U= 10 x 3 m/s = 30 m/s. Upward movement of the ball when a ball is thrown vertically
