Question

A ball is thrown straight up with an initial speed v. The diagram below is a graph of the height versus time for the motion of the ball.

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

1. instantaneous velocity

2. average velocity

3. none of the above acceleration

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

1. greater

2. the same

3. smaller

1. zero

2. indeterminate

3. a positive non-zero value

4. a negative non-zero value

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

1. zero

2. indeterminate

3. a positive non-zero value

4. a negative non-zero value

the slope of a position time graph gives instantaneous velocity
