1.) The bat exerts a force on the ball. This is the action force. The ball exerts an equal and opposite force on the bat. This is the reaction force.

2.) True! The force of the bug on the windshield is equal to the force of the windshield on the bug, only in the opposite direction.

3.) This is Newton’s third law and the total momentum of the two objects before the collision is the same as the total momentum of the two objects after the collision. (Reaction) The momentum of each object may change, but the total momentum must remain the same.

a toy dart gun generates a dart with .140kg.m/s momentum and a velocity of 4m/s. what is the mass of the dart in grams?

sleet_krkn [62]

Answer: m = 0.035kg = 35g

Explanation: Momentum p=0.140kgm/s

Velocity v=4m/s

Mass m=?

Formula-

Momentum depends on the mass of the object in motion and its velocity.

The equation for momentum is

p = mv

m = p/v

m = 0.140/4

m = 0.035kg

m = 35g

Hence, in the toy dart gun mass of the dart is 0.035kg.
