You measure 20 kg cart moving at a velocity of 2 m/s. 3 seconds later it is moving at a velocity of
10 m/s. what is the force acting on the cart?

53.3 N force acting on the cart.

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

best answer is f

a1 = unhealthy

a2= healthy

a3= healthy
