1) The diagram below shows a 0.1-kilogram apple attached to a branch of a tree 2 meters above a spring on the ground below. The apple falls and hits the spring, compressing ito. I meter from its rest
position. If all of the gravitational potential energy of the apple on the tree is transferred to the spring
when it is compressed, what is the spring constant of this spring?
APPLE
2 m
A) 10 N/m
B) 40 N/m
C) 400 N/m
D) 100 N/m

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?
