300 kg moving with a velocity of 10 m/s. *
(2 Points)
3000 J
0 15000 J
30000 J
1500 J​

Answer 1

Answer:

15000 J

Explanation:

K.E 1/2 mv^{2}

1/2*300*10*10

=15000J answer

Answer 2

Given : Ball of mass  = 300 kg

             Velocity of the ball = 10 m/s

To Find : Kinetic Energy.

Solution :

Mass of the ball m= 300 kg

Velocity of the ball v = 10 m/s

Kinetic Energy of the ball = $\[\frac{1}{2}m{v^2}\]$

Kinetic Energy of the ball = $\[\frac{1}{2} \times 300 \times {(10)^2}\]$

Kinetic Energy of the Ball = 15000 J.

Hence, Kinetic Energy of the ball is 15000 J.

=15000J
