A65 On a linear air-track the gliders float on a cushion of air and move with negligible friction. One such glider of mass 0.50 kg is at rest on a level track. A student fires an air rifle pellet of mass i.5 x 10 kg at the glider along the line of the track. The pellet embeds itself in the glider which recoils with a velocity of, 0.33 ms. (a) State the principle you will se to calculate the velocity at which the pellet struck the glider. Calculate the velocity at which the pellet struck.

A65 On a linear air-track the gliders fioat on a
cushion of air and move with negligible
friction. One such glider of mass 0.50 kg is at
rest on a level track. A student fires an air rifle
pellet of mass i.5 x 10 'kg at the glider along
the line of the track. The pellet embeds itself in
the glider which recoils with a velocity of,
0.33 ms.
(a) State the principle you will t:se to
calculate the velocity at which the pellet
struck the glider.
Calculate the velocity at which the pellet
struck.
(b) Another student repeats the experiment
with the air-track inclined at an angle of 2
to the horizontal. Initially, the glider is at
rest at the bottom of the track. After the
impact the glider recoils with the same
initial velocity but slows down and stops
momentarily further along the track.
Explain in words how to calculate how far
along the air track the glider moves before
stopping instantancously.
