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.

Answer:

h = 1.8 m

Explanation:

The initial velocity of the glove, u =- 6 m/s

We need to find the maximum height of the glove. Let it is equal to h. Using equation of kinematics. At the maximum height v = 0

v^2-u^2=2ah, h is the maximum height and a = -g

0^2-(6)^2=2\times (-10)\times h\\\\h=\dfrac{36}{20}\\\\h=1.8\ m

Hence, it will go up to a height of 1.8 m.
