i am not 100% sure, but i would go with D

Answer 4

A 2.5 kg sledge hammer hit a cement block with a force of 6.0 Newtons.

How does the force the sledge hammer exerted on the cement block compare with the force the cement block exerted on the sledge hammer?

A.
The force the sledge hammer exerted on the cement block is greater in magnitude and opposite in direction to the force the cement block exerted on the sledge hammer.

B.
The force the sledge hammer exerted on the cement block is equal in magnitude and in the same direction as the force the cement block exerted on the sledge hammer.

C.
The force the sledge hammer exerted on the cement block is less in magnitude and opposite in direction to the force the cement block exerted on the sledge hammer.

D.
The force the sledge hammer exerted on the cement block is equal in magnitude and opposite in direction to the force the cement block exerted on the sledge hammer.

Answer 5

Force is mass times acceleration, the answer to your initial question is C.

Answer 6

And the answer is D to your second question.

An ice hockey player hits a puck with a mass of 0.42 kg. The puck travels at a velocity of 28 m/s for 1.6 s until the goalie stops it.

What additional information is required to determine the weight of the puck?
A. the weight of the hockey player
B. the force applied by the hockey stick
C. the force applied by the goalie
D. the force of gravity acting on the puck

Answer 8

The answer is D, weight only has to do with the force of gravity on the object
