A frictionless incline is 5.00 m long (the distance from the top of the incline to the bottom, measured along the incline). The vertical distance from the top of the incline to the bottom is 2.26 m. A small block is released from rest at the top of the incline and slides down the incline.
(i) How long does it take the block to reach the ground?
A skier starts stationary at the top of a 20 m long slope and begins to descend. The
skier's acceleration is 0.2 m/s?. At the bottom of the slope the skier glides under a
frictional deceleration of 0.1 m/s?.
(1) Calculate the speed of the skier at the bottom of the slope.
(ii) Calculate how far the skier glides before coming to rest.
An athlete of mass 70 kg begins to run, and is observed to have velocity over the first 5
strides of 3.0, 4.2, 5.0, 5.6, and 6.0 m/s. For each stride calculate the net impulse delivered
due to the horizontal ground reaction force.
*12-116. The automobile is
originally at rest s = 0. If it
then starts to increase its
speed at v = (0.05t²) ft/s²
, where t is in seconds, de-
termine the magnitudes of
its velocity and acceleration
at s = 550ft.

- A student is asked to measure the acceleration of a glider on a frictionless, inclined plane, using an air track, a stopwatch, and a meterstick. The top of the track is measured to be 1.774 cm higher than the bottom of the track, and the length of the track is d = 127.1 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, respectively.
