Gravitational potential energy is energy an object possesses because of its position in a gravitational field. The equation for gravitational potential energy is GPE = mgh.
GPE = 1200(1.6)(350) = 672000 J
Hope this answers the question. Have a nice day.
968 j or kg because it cannot lose any of it energy and cannot gain any extra mass from nothing
Answer:
Making a vertical vector, we have a starting point at (-5,2) and an end point at (5,2) that will give us a vector of magnitude of 10 units.
Explanation:
In order to make vectors that have a magnitude of 10 units, the distance between the starting and ending points must be equal to 10.
The easiest way is to set points on either an horizontal or vertical line to make horizontal or vertical vectors.
We can have starting point at (-5,2) and then move up 10 units so we will be at the ending point (5,2), thus the distance between them is 10 units so the vector has a magnitude of 10 units.
We can verify that using the formula for the magnitude which requires first to find the vector.

So for the points we have

We can work with each component, for the x component we have 5-(-5) which give us 10 and for the y component we have 2-2 which give us 0, so the vector is

Thus its magnitude is

Thus we have verified our vector has a length 10.
Contact area is not a factor of the amount of friction force acting between two bodies in contact, preventing rolling or sliding
Reasons:
- Friction force is the product of the normal reaction and the coefficient of friction.
- The coefficient of friction is higher in softer tires than hard tires which are required to be wider to reduce the pressure that can cause deformation withstood by hard tires.
- The wide tires in drag racing cars can be thought of being made from the soft compound tire material having a higher coefficient of friction that increases the friction force.
Other advantages of wide tires are;
- Shorter stopping distance
