Question

A car travelling with a uniform acceleration of 3m/s². If its starting velocity was 2m/s. Calculate its velocity after it has travelled for 10m

Answer 1

Answer:

The equation of motion to be used here is v = u + at

u : initial velocity

a : acceleration

t : time of motion

v : velocity at the end of t second.

u = v - at

u =10 - 3*2

u =10 - 6 = 4 m/s

Velocity at the start is 4 m/s

Answer 2

Answer:

8m/s

Explanation:

use v²= u²+ 2as

u= 2m/s

a= 3

s= 10

solve

v² = 4+2×3×10

v²= 64

v= 8m/s
