An ice skater throws a 0.23 kg snowball with a velocity of 13 m/s. ice snowball 13 m/s

(a) (i) State the equation linking momentum, mass and velocity.

(ii) Calculate the initial momentum of the snowball.
initial momentum = kg m/s

(b) When the skater throws the snowball forwards, she slides backwards on the ice.
Explain why she moves in this direction. ​
