Question

(a) What does the slope of the graph at location A indicate?

acceleration

instantaneous velocity

average velocity

none of the above

(b) What is the slope of the graph at location B compared to the slope at location A?

smaller

the same

greater

(c) What is the slope of the graph at location C?

zero

indeterminate

a positive non-zero value

a negative non-zero value

(d) What is the velocity of the ball at location C?

zero

indeterminate

a positive non-zero value

a negative non-zero value

(e) What is the acceleration of the ball at location C?

zero

+ 9.81 m/s2

? 9.81 m/s2

Explanation / Answer

a) h = u.t - 1/2.g.t2

dh/dt = u - 2.g.t

It shows Instantaneous velocity

b) slope at B is less than slope at A

c) slope at C = 0

d) velocity at C = 0

e) - 9.81 m/s^2
