Question

. A toy scooter is having mass of 20 kg. It runs with a speed of 1 ms! What is the kinetic energy of the scooter ?​

Answer 1

Answer:

10J

Step-by-step explanation:

Mass of the toy(m)=20kg

Speed(v)=1m/s

Kinetic Energy={1×20×(1)^2}/2 (K.E=1/2×mv^2)

=10J

Answer 2

Concept:

Kinetic energy of an object is the energy that it possesses due to its motion.

Speed of an object is the magnitude of the change of its position over time.

Given:

A toy scooter is having a mass of 20 kg.

Its speed is 1 ms.

Find:

We need to find the kinetic energy of the scooter with the data given.

Solution:

We know that the formula for calculating kinetic energy is:

KE=(1/2) mv²

where m is the mass and v is the velocity/speed of the scooter.

We will substitute the given values in the formula:

=(1/2) ×20×1²

=(1/2)×20

=10 joules.

Therefore, the kinetic energy of the scooter is 10 joules.
