Question

A child operating a radio-controlled model car on a dock accidentally steers it off the edge. The car's displacement 0.91 s after leaving the dock has a magnitude of 7.0 m. What is the car's speed at the instant it drives off the edge of the dock?

Answer 1

Step-by-step explanation:

distance, d = 7 m

time, t = 0.91 s

speed, v = distance / time

v = 7 / 0.91

v = 7.69 m/s

Thus, the speed is 7.69 m/s
