A ball is thrown upward at a speed v0 at an angle of 58.0˚ above the horizontal. It reaches a maximum height of 8.0 m. How high would this ball go if it were thrown straight upward at speed v0?

11.245 m

Explanation:

The vertical component of the initial velocity v0 is

This makes the ball reach a maximum height of 8m. If we apply the conservation law of mechanical energy, its kinetic energy is converted to potential energy when it travels to the maximum height

where m is the mass and h = 8 m is the maximum vertical distance traveled, g = 9.81m/s2 is the gravitational acceleration

we can divide both sides by m

So if the ball is directed fully upward at v0 speed then we can apply the same equation to find the new H

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.
