Two boys push horizontally a 30Kg bicycle and it accelerates at 1.5 m/s2. If the sum of opposing force is 40N. What force must they be exerting on it.

Answer :

Today at 3:20 AM

Fnet = mass × acceleration

Fpush (force by the boys) - 40 = (30)(1.5)

Fpush - 40 = 45

Fpush = 45 + 40

Fpush = 85 N

So, the boys are exerting a force of 85 N on the bicycle.
