A car of mass 30 kg is pushed along a horizontal path by horizontal force of 8 N and moves with a constant velocity.

      

A car of mass 30 kg is pushed along a horizontal path by horizontal force of 8 N and moves with a constant velocity. The force is then increased to 14N. Determine:
a) The resistance to the motion of the cart;
b) The acceleration of the cart.

  

Answers


John
a) Resistance = 8 N

b) F = ma, 14 - 8 = 30a

a = $\frac{6}{30}$

= 0.2 m/s2
