energy will be
a) 5000 J
O
b) 4500 J
O c) 9000
O d) 450​

Answer 1

Answer :-

The kinetic energy of the vehicle is 4500J.

Step-by-step explanation:

To Find :-

• The kinetic energy of vehicle.

★ Solution

Given that,

• The mass of vehicle = 90kg
• The speed of vehicle = 10 m/s

We know,

Kinetic energy = 1/2m(v)²

Where,

• m = Mass
• v = Speed

Therefore,

⇒ 1/2m(v)²

⇒ 1/2 × m × (v)²

⇒ 1/2 × 90 × (10)²

⇒ 1/2 × 90 × 100

⇒ 1 × 90 × 50

⇒ 90 × 50

⇒ 4500 J

Hence,

The kinetic energy of vehicle is 4500J.

Formula used :-

• Kinetic energy = 1/2m(v)²
