Question

With your hand, you push back a toy car slowly and at constant speed against a rubber band launcher, stretching the rubber band. You then hold the car still for a short period of time, and then let go. The rubber band un-stretches and launches the car forward. The car then moves along a flat, carpeted section of floor, then moves up a low-friction ramp. The motion detector was able to capture the entire sequence of events, beginning with when you were pushing the car against the rubber band. A. Circle the number on the speed-time graph that best represents the data recorded by the motion detector. WA huhu B. On the graph you chose, mark an X exactly where you let go of the car. Marka Y on the graph when the car left contact with the rubber band. Mark a Z on the graph when the car first reached the ramp. C. Consider the interval of time while you were pushing the car drainst the rubber band at constant speed. Draw a G/R energy diagram of all the interactions the toy car is involved in during that interval

Answer 1

when you ppusn your car back it moves with constant speed . During this time graph will be time. Therefore Then it stops sour short period of v will become zero Then to elastic can, and potential energy will be transfered it will increase in form of equation 14x² = 1 mı? ova JKR = Se a . It is almost einer linery=ma Then it cleaves contact with spring and a stares moving on carpented hwor, so speed decreare due to friction. La

Then when it climbs ramp, gravity also strars decelerating it so fall of speed is more steep. Graph 3 B.
