Lauryn serves a volleyball with a mass of of 2.1 kg the ball leaves her hand with a speed of 30m/s find the energy of the ball

m = mass of the volleyball = 21. kg

v = speed of the volleyball as it leaves her hand = 30 m/s

KE = kinetic energy of the volleyball

kinetic energy of the volleyball is given by the formula

KE = (0.5) m v²

inserting the above values in the formula

KE = (0.5) (2.1) (30)²

KE = (0.5) (2.1) (900)

KE = (0.5) (1890)

KE = 945 Joules

hence the energy of the volleyball comes out to be 945 Joules

in this image, you can see solar radiation going through ocean water.

no image, but probably absorption

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
