Answer:
53.3 N force acting on the cart.
Step-by-step explanation:
Given data:
Weight/Mass: 20kg
Initial speed (Vi): 2 m/s
Final speed (Vf) : 10m/s
time: 3 seconds
Force:?
Formula:
F: (Mass) x (accerlation)
F= m x a
Vf = Vi + at
a = Vf - Vi / t
a = (10m/s) -(2m/s) / 3s
a = (8m/s) / 3s
a= 2.6 m/s^2
F = m x a
F = 20kg x 2.6 m/s^2
F = 53.3 N
