Astudent must design an experiment to determine the acceleration of a cart that rolls down a small incline after it is released from rest. the student has access to a timer, a meterstick, and a slow-motion camera that takes a photograph every of a second. the angle that the incline makes with the horizontal is unknown, and the length of the incline is unknown. which of the following procedures could the student use to determine the cart's acceleration? select two answers. a. use the meterstick to measure the vertical height of the incline, and use the timer to record the time it takes for the cart to travel down the incline use the timer to record the time it takes the cart to travel alongside a meterstick that is attached to the incline. b. use the slow-motion camera to film the cart as it rolls down the incline alongside a meterstick that is attached to the incline. c. use the slow-motion camera to film the cart as it rolls down the incline alongside a timer that is attached to the incline.

A. Use the meterstick to measure the vertical height of the incline, and use the timer to record the time it takes for the cart to travel down the incline Use the timer to record the time it takes the cart to travel alongside a meterstick that is attached to the incline.

C. Use slow motion camera to film the cart as it rolls down the incline alongside the timer that is attached to the incline.

Explanation:

Since acceleration is change in velocity with respect to time. Two things that are important are the velocity of the cart and time taken by the cart to accelerate down the plane.

Note that the higher the height of the inclined plane, the more the acceleration. This shows the importance of knowing the height of the inclined plane.

Also we need to know the time taken by the body to accelerate down the plane and as such the importance of the timer.

To get the velocity, we can monitor the velocity of the body through the use of camera, the velocity can be determined at each time interval after the picture has been taken.

the answer would be 32*f
