Question

A uniformly accelerated body traveling along a straight line with initial velocity 2 m/s passes over 24 meter from start in 3 seconds. Calculate the uniform acceleration and velocity it will acquire when it has passed over 4 meter from the start

Answer 2

Answer:

Explanation:

Case 1

u=2m/s

s=24m

t= 3s

s =ut + 1/2 at*2

s= 2 x 3 + 1/2 a x 9

=> 24 - 6 =9a/2

18 x 2/9 = a

a= 4m/s*2

case 2

since acceleration is uniform so,

t = 1s

speed = distance / time

s = 4m/s

=> uniform acceleration= 4m/s*2  , Velocity = 4m/s
