Question

(a) Stone A leaves the player's hand with a velocity of 2.90 m/s.

The mass of stone A is 17 kg.
(i) State the formula linking momentum, mass and velocity.

(ii) Show that the momentum of stone A is approximately 50 kg m/s.
(1)
(2)

Answer 1

(a)(i) momentum(kg m/s) = mass x velocity
p=mv

(a)(ii) 17 x 2.90 = 49.3

49.3 is approximately 50 kg m/s

Explanation: mass of stone A is 17 kg and the velocity of stone A is 2.90 m/s. To find momentum is to times mass and velocity.
