Answer:
1.#potential energy = PE, m = mass in kg, g = force of gravity, h= vertical height above the ground. ** means to the power of ie exponent. * means multiply.
PE = mgh
300 = m(10)(15)
m = 300/(10)(15)
m= 2kg
2. KE = 1/2 mv**2
= 1/2(50)(50)**2
= 2500 joules
Explanation
Is as in solution
Answer:
Weight is a force.
Explanation:
Force acting on an object is defined in terms of mass and its acceleration. Its mathematical force is given by
F = ma
Weight of an object is force that the Earth exerts on an object. It can be given by the formula as follows :
W = mg
g is acceleration due to gravity on the surface of earth
Hence, the correct option is (d).
Answer:
Pine cone 2 does, the more mass an object has, the more kinetic energy is has.

I took the test, its constructive interference
Edit: this is kind of a trick question. took the test again it was the same question yet this time the answer was destructive. Good luck with that
