Question

What is the kinetic energy of a 1500kg object moving at a velocity of 10m/s

Answer 1

Given:

• Mass, m = 1500 kg

,

• Velocity, v = 10 m/s

Let's find the kinetic energy.

To find the kinetic energy, apply the formula:

`KE=(1)/(2)mv^2`

Where:

KE is the kinetic energy

m is the mass of the object in kg = 1500 kg

v is the velocity in m/s = 10 m/s

Plug in values into the formula and solve for KE:

`\begin{gathered} KE=(1)/(2)mv^2 \\ \\ KE=(1)/(2)*1500*10^2 \\ \\ KE=750*100 \\ \\ KE=75000\text{ J }\approx75\text{ kJ} \end{gathered}`

Therefore, the kinetic energy is 75 kJ.

ANSWER:

75 kJ
