What is the velocity of a 0.06
kg ball moving with 75 J of energy?

The ball moves at 50 m/s

Explanation:

Kinetic Energy

Is the energy that it possesses an object of mass m due to its motion at speed v. The kinetic energy is calculated as follows:

If we know the value of the kinetic energy and need to calculate the speed, we can solve it for v:

Since the ball has a mass of m=0.06 kg and moves with a kinetic energy of K=75 Joule:

v=50 m/s

The ball moves at 50 m/s

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
