Explanation:
Renewable resources are going to be important in our future because if we use up all of our NON-renewable resources now, then we’ll still have the renewable resources to depend on.
I hope this helped! :-)
1350kgm/s
Explanation:
Given parameters:
Mass of Sam = 75kg
Velocity = 18m/s
Unknown:
Momentum = ?
Solution:
Momentum is the property of a moving body with respect to its mass and velocity.
Objects in motion have momentum. The more the velocity of a body, the more its momentum. Also, the more the mass of an object, the more momentum it possess.
Momentum is a function of the mass and the velocity of a body
Momentum = mass x velocity
Momentum = 75 x 18 = 1350kgm/s
