Answer:4.93 m/s
Explanation:
Given
height to reach is (h )1.24 m
here Let initial velocity is u
using equation of motion
here Final Velocity v=0
a=acceleration due to gravity
u=4.93 m/s
An object accelerates to a velocity of 230 m/s over a time of 2. 5 s. The acceleration it experienced was 42 m/s2. Its initial velocity will be 125 m/s
final velocity = 230 m/s
time = 2.5 second
acceleration = 42
initial velocity = ?
acceleration = final velocity - initial velocity / time
42 = (230 - u) / 2.5
u = 125 m/s
Its initial velocity will be 125 m/s
