Question

A leopard is running with a velocity of 3 m/s. it then accelerates at 2 m/s² for 4 seconds.

use the formula:
v = u + at
to work out the final velocity of the leopard.

please can people reply and help me thank you

Answer 1

Using the formula:

v = u + at

Here s is distance, u is initial velocity, v is final velocity, a is acceleration and t is time.

In this case, u = 3m/s, a = 2m/s^2, t = 4s and we want to find final velocity, v, s, v = u + at

v = 3 + 2(4) = 11m/s

Hope this helps!
