Answer 1

Answer:

(b) ()

(i) Derive and state the equation linking acceleration, change in velocity and time

using a velocity time graph.

(ii) The coin hits the ground in a time of 0.62 s with a velocity of 6.1 m/s.

V = 0.62, m/s -6-1

Calculate the acceleration of the coin as it falls.

Give the unit.
