Q1. A student is asked to determine the acceleration of a glider on a frictionless, inclined plane, using an air track, a stopwatch, and a meter stick. The top of the track is measured to be 1.77 cm higher than the bottom of the track, and the length of the track is d = 127.10 cm. The cart is released from rest at the top of the incline, taken as x = 0, and its position x along the incline is measured as a function of time. For x values of 10.0 cm, 20.0 cm, 35.0 cm, 50.0 cm, 75.0 cm, and 100 cm, the measured times at which these positions are reached (averaged over five runs) are 1.02 s, 1.53 s, 2.01 s, 2.64 s, 3.30 s, and 3.75 s, correspondingly.

Q2. Dan is gliding on his skateboard at 2m/s. He suddenly jumps backward off the skateboard, kicking the skateboard forward at 7.00m/s (as measured by an observer on the ground). Dan's mass is 50 kg and the skateboard's mass is 5.00 kg.
