A physics student playing with an air hockey table (a frictionless surface) finds that if she gives the puck a velocity of 3.78 m/s along the length ( 1.79 m ) of the table (the x-direction) at one end, by the time it has reached the other end the puck has drifted a distance 2.55 cm to the right (the y-direction). The puck still has a x-component of its velocity of 3.78 m/s when it reaches the other end of the table.
She concludes correctly that the table is not level and calculates its inclination (tilt) from the above information.
What is the angle of inclination?
Solutions
Expert Solution
consider the motion along the X-direction :
vox = velocity along x-direction = 3.78 m/s
x = distance travelled = 1.79 m
t = time of travel = ?
using the equation
x = vox t
1.79 = (3.78) t
t = 0.474 sec
consider the motion along the y-direction
voy = initial velocity along the y-direction = 0 m/s
a = acceleration = g Sin
y = displacement = 2.55 cm = 0.0255 m
t = time = 0.474 sec
Using the equation
y = voy t + (0.5) a t2
0.0255 = 0 (0.474) + (0.5) (9.8 Sin)
(0.474)2
Sin
= 0.0232

2. a)
A 0.20 kg hockey puck on a frictionless surface is hit with a
stick. The force of the stick on the puck, during the 0.4 seconds
while they are in contact, causes the puck to go from rest to 36
meters per second east. What was the magnitude of the average force
of the stick on the puck while they were in contact?

A hockey puck sliding on a frictionless surface strikes a box at rest. After the collision, the two objects stick together and move at some final speed. Which of the following describes the change in momentum and energy of the puck during the collision? The puck loses some, but not all, of its original momentum and mechanical energy. One cannot determine if the momentum or energy of the puck is conserved without knowing the final velocities and masses two objects. The puck conserves...
