Answer:
Explanation:
As we know that the centripetal force is given as
now we will have to find the rate of change in force with respect to its radial distance
so we have
so we have
m = 1000 kg
v = 13.89 m/s
r = 200 m
now we have
The ping pong ball was stopped because it lost its kinetic energy as it was made of plastic. The wooden ball gained the kinetic energy from the desk as it was also made out of wood.
That's my reasoning, Hope it is correct!

Galaxies are comprised of groups of stars circling a common gravitational point (which is theorized in the Milky Ways case to be a black hole). The answer is True.
Answer:
123 km/h
Explanation:
The distance between the Jeep Wrangler and the Ford Taurus is increasing.
Let us consider the north direction as positive when observing from the ground
So, the south direction will be negative
But when the observer is one of the cars the direction will be the same i.e., moving away from each other, so the velocity will be added.
Hence velocity of the Jeep relative to the Ford will be
Velocity of the Jeep + Velocity of the Ford
= 74+49 = 123 km/h
∴ Velocity of the Jeep relative to an observer in the Ford is 123 km/h
