Hey
The formula of kinetic energy is 1/2mv^2
So it depends on mass and velocity
As mass increases , kinetic energy increase .
So option b , the first rider had more mass is correct z
Answer: b
Explanation:
Ec= (1/2)m × v^2
By the formula, you can see that the bigger the mass, the bigger the Cinetic Energy.
<span>a+b= ?
3i +3j + (3i -3j) = ?
3i + 3j + 3i -3j =?
= 6i + 0j</span>
J.J. Thompson is the scientist who recieved credit for discovering them.
