Answer 17

-9.2 ms ^-2

Question 18

What does acceleration equal for downward motion due to gravity?

Answer 18

9.8 ms^-2

Question 19

What is velocity?

Using differentiation

Answer 19

Velocity, v, is the rate of change of displacement, s, with respect to time, t.

v=ds/dt

Question 20

What is acceleration?

Using differentiation

Answer 20

Acceleration, a, is the rate of change of velocity with respect to time

a = dv/dt = d^2s/dt^2

Second derivative

Question 21

When does maximum/minimum displacement occur?

Answer 21

When velocity =0

When ds/dt =0
