Answer:
I A 1000 kg car is traveling at 20 m/s. How much kinetic energy does it. Here, Given- mass=1000kg Speed=20m/s Formula ...
Missing: 13.4m/s | Must include: 13.4m/s
Explanation:
Answer:
The normal force will be lower than the gravitational force acting on the car. Therefore the answer is N < mg, which is <em>option B</em>.
Explanation:
Over a round hill, the centripetal force acting toward the the radius of the hill supports the gravitational force (mg) of the car. This notion can be expressed mathematically as follows:
At the top of a round hill

At the foot of a round hill

The basketball is gaining kinetic and losing potential energy is the answer
