Answer:

250s

Explanation:

Given parameters:

Mass  = 50kg

Speed  = 10m/s

Force  = 2N

Unknown:

Time the force was acting  = ?

Solution:

To solve this problem, we use the equation of motion from the second law of Newton:

            Ft  = mV

F is the force

t is the time taken

m is the mass

V is the velocity

          2  x t  = 50 x 10

               t  = 250s
