A block is launched up an inclined plane. After going up the plane, it slides back down to its starting position. The coefficient of friction between the block and the plane is 0.3 . The speed of the block when it reaches the starting position on the trip down:
a. is the same as the launching speed. b. is less than the launching speed. c. is more than the launching speed. d. cannot be compared to the launch speed with the information given.
Question 2

b. is more than the time for the trip down.
c. is less than the time for the trip down.
d. cannot be found compared without knowing the angle of inclination.
