Answer:
true cuase it is true its not false
Answer:
both kinetic energy and potential energy
Technically friction is acting on the car because it is still rubbing against the street and gravity is pulling the car down preventing it from floating??? lol
The elevator has constant acceleration upward
Given that a student that weighs 436 N is standing on a scale in an elevator and notices that the scale reads 498 N.
The formula of force can be derived from the Newton's second law of motion, which states that the force exerted by any object equals mass times the acceleration of that object i.e., F = ma
Net force = mg + ma
498 = 436 + ma
62 = 436 a/ 9.8
a = (62 x 9.8) / 436
a = 1.39 m/s²
Hence, it is clear that the elevator has constant acceleration upward.
