Fig. 1.1 depicts an ice-hockey player skating on ice. He is getting ready to strike the solid disc known as a puck. The disc, with mass 0.16 kg, is travelling horizontally across the ice at 15 m/s.
(a)[2]
Calculate the magnitude of the disc's momentum.
(b(i))[1]
State the magnitude of the impulse acting on the disc and the direction, in degrees, of the impulse relative to the original direction of travel.
(b(ii))[4]
Determine the magnitude of the new momentum of the disc and its new direction relative to the original direction of travel by drawing a scale diagram.
