Question

.
8 An object of mass 15 kg is moving with a uniform velocity of 4 m/s. what is the kinetic energy
possed by object​

Answer 1

Answer:

120kgm/s²

Explanation:

k.e=½*mv²

=½*15*(4)²

=½*15*16

=15*8=120kgm/sec²

Answer 2

Given :

• An object of mass 15 kg is moving with a uniform velocity of 4 m/s.

To find :

• What is the kinetic energy possessed by object.

Know terms :

• Mass (m) = 15 kg.
• Speed (Velocity) = 4 m/s.

Using formula :

→ Kinetic energy = 1/2 mv².

Calculations :

→ Kinetic energy = 1/2 × 15 × 4²

→ Kinetic energy = 120 J

Therefore, 120 Joule is the kinetic energy possessed by object.
