106.5N
Explanation:
Given parameters:
Mass of cart = 75kg
Velocity = 4.4m/s
time taken = 3.1s
Unknown:
Force = ?
Solution:
To solve this problem, we are going to apply newton's second law of motion. The law states that "the acceleration of a body is directly proportional to the force on the body and inversely proportional to the mass".
F = m x a
F = force on body
m = mass of body
a = acceleration of the body
But we know that acceleration is the change in velocity with time of a body;
a = 
F = m x 
V is the velocity
t is the time taken
F =
= 106.5N
