Question

HELP!
I need to design an experiment that reads the acceleration of a toy car going down a ramp.

All I can use are:
- Toy Car
- Two Ramps (one must be steeper)
- A meter stick
- A Calculator
- A Stopwatch

Any help is highly appreciated.
Thanks.

Answer 1

1)Put your toy car at top of ramp which initial velocity = 0.

2)Released the car let it go free acceleration downward.

3)Record the time that car go from top of the ramp to ground 10 times.

4)Use the formula S=ut+(1/2)at^2 which all measure is on the ramp
u = 0 , S=distance travelled by toy car(the length of the slope), t=time taken(which you recorded with stop watch, take average of 10 times),a=acceleration(you wish to find this)

5)Find the acceleration at (4) with the formula.

6)Complete.
