Question

A cat is moving at 18 m/s when it accelerates at 4 m/s2 for 2 seconds. what is his new velocity?

Answer 1

Velocity =18
Velocity at 2 seconds=18+4+4=26

Answer 2

Answer:

26m/s

Explanation:

Acceleration is the change in velocity of a body with respect to time. Mathematically,

Acceleration = change in velocity/time

Acceleration = final velocity (v) - initial velocity (u)/time (t)

Given a = 4m/s², v = ? u = 18m/s, t = 2seconds.

Substituting in the given formula,

4 = v-18/2

8 = v-18

v = 8+18

v = 26m/s

The new velocity of the body is therefore 26m/s
