Question

find the kinetic energy of a ball of mass 500g moving with a velocity of 8m/sfind the kinetic energy of a ball of mass 500 gram moving with a velocity of 8 metre per second ​

Answer 1

Answer:

KE=1/2×mass×velocity squared

=1/2×500× 8 squared

=250×64

=16,000 Joule

Answer 2

Question:

Find the kinetic energy of a ball of mass 500g moving with a velocity of 8m/s.

Answer:

The kinetic energy of ball is 16000 J.

Explanation:

Given:

Mass of ball or m = 500 g

Velocity or v = 8 m/s

To find:

Kinetic energy = ?

Solution:

Kinetic energy = $\frac{1}{2} m {v}^{2}$

$= \frac{1}{2} \times 500 \times {8}^{2}$

$= \frac{1}{2} \times 500 \times 64$

$= 250 \times 64$

= 16000 J

Therefore, The kinetic energy of the ball is 16000 J.

Kinetic Energy:

• The energy of a body due to its motion is called its kinetic energy.

• It depends on the mass of the body and its speed
