Physics Hw Question?

Question

A hockey player takes a slap shot at a puck
at rest on the ice.
Assume: The time of contact is 0.013 s.
The puck glides over the ice for 11.2 ft
without friction, at which point it runs over a
concrete surface. The puck then decelerates
at a uniform rate of 31.3 ft/s2.
If the velocity of the puck is 57 ft/s after
traveling 80.3 ft from the point of impact,
what is the average acceleration imparted to
the puck by the hockey stick?
Answer in units of ft/s2.

This problem was done previously on here but the answer was wrong I have tried everything.

Part b) How far does the puck travel before stopping?

Part c) What is the total time the puck is in motion, neglecting contact time?

Answer 1

wow i am in physics rite now and i have no clue how to do that
