Question

question #3 a golfer swings his club and strikes a golf ball. according to newtons 3rd law of motion, which of the following is a reaction to the club pushing on the golf ball? the golfer pushing on the club. the golf ball pushing on the player. the club pushing on the golfer. the golf ball pushing on the club. question #4 which of the following would have the least momentum? a bug traveling at 0.5m/s. a bug traveling at 1.0m/s. a bug traveling at 1.5m/s. a bug traveling at 0.75m/s.

Explanation:

Step1: Recall Newton's 3rd law

For every action, there is an equal and opposite reaction. The action - reaction pair acts on two different objects. When the club pushes on the golf ball, the reaction force is the golf ball pushing on the club.

Step2: Analyze Question #4

Momentum is given by the formula $p = mv$, where $m$ is mass and $v$ is velocity. Assuming the mass of the bug is constant, the lower the velocity, the lower the momentum. Among the given velocities of the bug ($0.5m/s$, $1.0m/s$, $1.5m/s$, $0.75m/s$), the lowest velocity is $0.5m/s$.

Answer:

Question #3: The golf ball pushing on the club
Question #4: A bug traveling at 0.5m/s
