The velocity of a car with a mass of 3.1 kg is equal to 6.22 m/s
<u>Given the following data:</u>
- Kinetic energy = 60 Joules
To calculate the velocity of the car:
Mathematically, kinetic energy is calculated by using the formula;
<u>Where:</u>
- K.E is the kinetic energy.
- M is the mass of an object.
- V is the velocity of an object.
Making V the subject of formula, we have:
Substituting the given parameters into the formula, we have;
Velocity, V = 6.22 m/s

<span>A star is born as a main sequence star when the temperature of the star's core becomes high enough to fuse hydrogen into helium. ... The story is different in evolved stars like giant stars. Once hydrogen in the core of the star is exhausted, the energy generation becomes small and the core starts to collapse. Hope this helps.</span>
