Question 1

A block slides down a frictionless inclined ramp and experiences no significant air resistance. If the ramp angle is 17.0° above the horizontal and the length of the surface of the ramp is find the speed of the block as it reaches the bottom of the ramp, assuming it started sliding from rest at the top.
◦ 114 m/s
◦ 19.6 m/s
◦ 7.57 m/s
◦ 10.7 m/s

Question 2

A bead is moving with a speed of 20 m/s at position A on the track shown in the figure. This track is friction-free, and there is no appreciable air resistance. What is the speed of the bead at point C?



◦ 34 m/s
◦ 20 m/s
◦ 0 m/s
◦ 69 m/s
◦ We cannot solve this problem without knowing the mass of the bead.
