Question

Lai threw a ball downwards with an initial velocity of 11.0 m/s. What is in meters the displacement of the ball during the 2.9 seconds after she threw it? (don't include units in the answer, use 10.0 m/s2 for g and use the upward direction as positive)

Answer 1

d = Vi t + (1/2) g t^2
d = 11 t + 5 t^2
