Question

A body starts from rest and moves with a uniform acceleration of 2 m/s² until it travels a distance of 625 m . Find its velocity.

Answer 1

Answer:

50 m/s

Explanation:

Given:

a = 2 m/s²

s = 625 m

u = 0 m/s

Using Kinematics law,

v² = u² + 2*a*s

   = 0 + 2*2*625

v² = 2500

thus v = 50 m/s

Answer 2

Answer:

Velocity = distance travelled / time taken + dir.

Dis. Travelled = 625 m

Time taken = 2mper sec.

Dir = x ( not given)

Therfore velocity is = 625/ 2 = 312.5 m/ sec. I hope it helps you
