TRUCK AND TRAILER 1
Type the formula for the trailer. Click "Test": x(t) =
Mr. Kambule is heading out for a weekend camping trip with his family. He needs his trailer hooked up to his truck. Hook it up for him: type the correct formula of motion for the trailer in the box and click "Test". You can try to find the correct formula for the trailer by
trial-and-improvement
- if the two vehicles do not move together so that the hookups match exactly, it is not correct. Then change your formula. Make sure that you use * for multiplication and t for the variable. But it is much more efficient to find the formula
algebraically
. To do this, you should first make sure whether the motion is linear or quadratic. If it is linear, the formula is of the form x(t) = x
0
+ vt, and you may probably already know that x
0
is the start position and v is the constant speed. You can find these values through measurement - simply click in the animation and read the necessary co-ordinates. Note that the position of the truck and the trailer is taken at their front wheels.
At what speed is Mr. Kambule travelling?
