Question

A hockey puck slides across an ice rink. Consider the origin to be at the center of the rink; the

plane of the rink is the xz plane. At time t=0.0 s a hockey puck is observed to be at location <-6,

0,-5> m. At time t=0.2 sec, the puck is observed at location <6, 0, 2> m.

a) What is the average velocity of the hockey puck during this time interval?

b) What is the magnitude of the average velocity?

c)

What is the unit vector in the direction of the velocity?

Answer 1

The drawing shows a top view of a hockey puck as it slides across frictionless ice. Three forces act on the puck, and it is in equilibrium. The force F is applied at the center and has a magnitude of 31 N. The force F1 is applied at the top edge, and F2 is applied half way between the center and the bottom edge. Find the magnitude of F1 and F2.

A 1.25kg hockey puck (puck A) slides across a frictionless sheet of ice and collides with a puck of unknown mass (puck B) head on. The collision is completely elastic, which means no kinetic enegy is lost in the collision. After the collision, puck A moves in the opposite direction at half of its initial speed. Find the mass of puck B.

A hockey puck is sliding on the smooth ice surface of a skating rink as shown in the figure above. The figure shows the puck’s position on the ice surface at a sequence of equally spaced times t0, t1, t2, t3 and t4. The x axis shown is parallel to the rink’s length and the y axis to its width. The marks along the axes are spaced 1 meter apart as are the successive positions of the puck. The unseen...

A hockey puck slides on ice (looking down on the ice from above; blue arrows are momentum, red line shows path); friction and air resistance are negligible. When the puck reaches location 2 it is struck hard by a hockey stick; the contact lasts a very short time. It then travels from 2 to 3 at nearly constant momentum. The magnitude of the puck's momentum is the same at locations 1 and 3. Which green arrow best indicates the direction of...

A local ice hockey team has asked you to design an apparatus for measuring the speed of the hockey puck after a slap shot. Your design is a 2.00-m-long, uniform rod pivoted about one end so that it is free to rotate horizontally on the ice without friction. The 1.30-kg rod has a light basket at the other end to catch the 0.163-kg puck. The puck slides across the ice with velocity v vector (perpendicular to the rod), hits the...
