Calculate the average net force.

Answer:
mass = 3950 kg
speed= 25m/ sec
time= 10.5 sec
force
[tex] \fbox{f = m.a}[/tex]
To find the force we need to find the Acceleration first.
accleration= change in Velocity/time
accleration= 25/10.5
accleration= 2.38 m/sec²
put the value of accleration in the formula of force
force = Mass . accleration
force = 3950 x 2.38
