The speed after 10 s is 20 m/s
<h3>What is the speed after 10 s?</h3>
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
