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
