Day 138: Testing Predictions for the Hot Wheels Challenge
The assignment that grades itself!
To be fair, friction played a large enough role that the cars fell short of their intended target. To show them that their projectile solution really works, we used a BeeSpi photogate timer to get the actual speed of the toy car as it left the table. After quick recalculation of the range, the cars landed in the cup no problem. I put some "no bounce foam" in the bottom of the cup to keep the car from bouncing out.
BeeSpi photogate timer (just as wide as the Hot Wheels track):
Hmm… It looks like PASCO doesn't sell no bounce foam anymore 😦
