terry physics pushes a 75kg lab cart so that is accelerates from rest with a velocity of 4.4m/s in 3.1 secounds. what is the for
svetlana [45]

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  = \frac{change in velocity }{time}

  F = m x \frac{V}{t}

V is the velocity

t is the time taken

   F = \frac{75  x  4.4}{3.1}   = 106.5N
