Question

A net force of 2800 N is applied to a 1400 kg automobile at rest. The speed of the automobile after 10 s will be:

Answer 1

The speed after 10 s is 20 m/s

What is the speed after 10 s?

Given that we have the following;

force = 2800 N

Mass = 1400 kg

time = 10 s

Recall that;

F = ma

F = force

m = mass

a = acceleration

a = F/m

a =  2800 N/1400 kg

a = 2 m/s^2

Now;

v = u + at

v = ??

u = 0 m/s

a= 2 m/s^2

t = 10 s

v = at

v = 2 * 10

v = 20 m/s
