Question

if a body is thrown upward with a velocity of 49 m/ s .find maximum height obtained and time to attain maximum height​

Answer 1

Answer:

Given Initial velocity of ball, u=49 m/s

Let the maximum height reached and time taken to reach that height be H and t respectively.

Assumption: g=9.8 m/s2 holds true (maximum height reached is small compared to the radius of earth)

Velocity of the ball at maximum height is zero, v=0

v^2-u^2=2aH

0−(49)^2 =2×(−9.8)×H

⟹H=122.5 m
