If you start rolling down this hill, your potential energy will be converted to kinetic energy. At the bottom of the hill ypu KE

Serjik [45]

Answer:

$v=\sqrt{(2x/m)}\ \ m/s$

Explanation:

Potential Energy= Kinetic Energy

Let $x$ be the value of Kinetic Energy.

We know that

$PE=KE=x\\x=\frac{1}{2}mv^2\\$

Make $v$ the subject of the formula to get speed at the bottom of the hill.

$v^2=2x/m\\v=\sqrt{2x/m}$

A water tank has a mass of 3.64 kg when empty and 51.8 kg when filled to a certain level. What is the mass of the water in the t

mrs_skeptik [129]

Subtract the total mass of the tank and water by the mass of the empty tank. That will yield the mass of the water.

51.8 - 3.64 = 48.16.

Your answer is 48.16 kg

Why does a force perpendicular to an objects velocity change the direction of the velocity but not its magnitude

inna [77]

Answer:

According to your question although I think an object undergoing uniform circular motion is moving with a constant speed. Nevertheless, it is accelerating due to its change in direction. The direction of the acceleration is inwards,therefore a force perpendicular to an objects velocity change the direction of the velocity but not its magnitude.
