Aman stands on the roof of a building of height 13.0m and throws a rock with a velocity of magnitude 34.5m/s at an angle of 26.1^\circ above the horizontal. you can ignore air resistance. calculate the horizontal distance from the base of the building to the point where the rock hits the ground?

Given that the man stands on the roof the building y =13 m high. Throws a rock with a velocity of v=34.5 m/s at an angle a=26.1 degrees above the horizon. Calculate the horizontal x distance covered by the rock. The problem can be solved using the equation of trajectory:

Y=xtan(a) + g(x^2)/2(v^2)((cos(a))^2) where g = 9.81 m/s^2

Substituting the given and solving for x= 21.65 m.

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.
