A 0.41 kg rock is projected from the edge of the top of a building with an initial velocity of
12.5 m/s at an angle 58◦
above the horizontal.
Due to gravity, the rock strikes the ground at
a horizontal distance of 17.7 m from the base
of the building. Building
17.7 m

How tall is the building? Assume the
ground is level and that the side of the building is vertical. The acceleration of gravity is
9.8 m/s

.
Answer in units of m.

The correct answer is c

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
