Shown below are two inclines. We will place identical carts on the top of each incline and
release them from rest. Both inclines have the same height and are frictionless.
B
A
θ
φ
1) Will the cart’s acceleration on A be greater than, less than or equal to its acceleration
on B? Explain.
The acceleration on A will be greater than the acceleration on slope B, as the amount of gravity
experienced by the cart will be greater on slope A.
2) Will the cart’s time down A be greater than, less than or equal to its time down B? Explain.
When the angle increases the time taken for the ball to roll down the ramp decreases, meaning A
will have a shorter time taken than B.
3) Will the cart’s average speed down A be greater than, less than or equal to its
average speed down B? Explain.
The average speed with A is the same as the average speed of B, due to the equation being
distance/time, as more distance is covered in less time and more time taken for less distance
average out.
4) Will the cart’s final speed at the bottom of A be greater than, less than or equal to its
final speed at the bottom of B? Explain.
The final speed for A will be the same as for B.
