Question

2. A volleyball player strikes a 3 kg volleyball with a velocity of 14 m/s. What is the kinetic energy of the volleyball?

Answer 1

Answer:

2. 294 j

3. 37500 J

Explanation:

Answer 2

Answer:

2)294 3)15

Explanation:

2)E=mv^2/2

E=3×14^2/2

E=3×196/2

E=3×98

E=294 J

3)E=mv^2/2

m=2E/v^2

m=2×750/10^2

m=2×750/100

m=750/50

m=15
