Question

If a small motor does 1.20x102 J of work to move a toy car 96 m,
how much force does it exert?

if the power dissipated in the process is 0.25W, calculate the time required.

if the acceleration produced is 0.014m/s2, determine the mass of the car.

Answer 1

Explanation:

Work=force×displacement

222.4=force×96

f=2.32

force=m×a

m=2.32÷0.014

165.7

P=E÷T

time=0.25÷222.4

0.00112
