A baseball strikes the catcher's glove with a horizontal velocity of 40 m/s. The mass of the baseball is 0.15 kg. The displacement of the baseball due to the deformation of the catcher's glove and the movement of the catcher's hand is 8 cm from the instant it first makes contact with the glove until it stops. a. How much kinetic energy does the baseball possess just before it strikes the glove

Sagot :

Answer:

the kinetic energy is 120 J

Explanation:

a. The computation of the kinetic energy before it strikes the glove is as follows:

As we know that

The Kinetic energy is

=  1 ÷ 2 × m × v^2

= 1 ÷ 2 × (0.15)(40^2)

= 120 J

Hence, the kinetic energy is 120 J
