A roofing shingle elevator is lifting a 30.0-kg package to the top of a building at constant speed. The angle between the elevat
or track and the horizontal is 75∘. The power of the elevator is 800 W. Part A Determine the vertical component of the speed with which the package is moving up. Assume no friction is exerted by the incline surface on the package.

Answer:
s=800 m
Explanation:
Given that,
Acceleration of a runner, a = 4 m/s²
Time, t = 20 seconds
We need to find the distance covered by her. Initially, she was at rest. It means its initial velocity is equal to 0. So, using second equation of motion as follows :
Herre, u = 0
So, she will cover a distance of 800 m.
