Question

question 14 (4 points) (01.10 lc) which of the following shows a change of velocity? a a car is at rest in a parking lot for two hours. b the basket on a slingshot ride goes up and then down. c hannah rides her bike at 5 miles per hours. d malik drives his car at 60 kilometers per hour.

Explanation:

Velocity is a vector quantity with magnitude and direction. A change in velocity can be due to a change in speed or direction. In option a, the car is at rest (zero velocity, no change). In option c, the speed is constant (no change in magnitude of velocity). In option d, the car has a constant speed (no change in magnitude of velocity). In option b, the basket on the slingshot ride changes direction as it goes up and then down, indicating a change in velocity.

Answer:

B. The basket on a slingshot ride goes up and then down.
