Question

6. 2 points SerCP10 3.P.029 A brick is thrown upward from the top of a bullding at an angle of 10 to the horizontal and with an Initlal speed of 11 m/s. If the brick is in flight for 3.2 s, how tall is the building? Need Help? Resd H

Answer 1

using the equation of linear motion we have

Y = Uyt - 0.5gt^2

-H = 11sin 10 * 3.2 - 0.5*9.8*3.2^2

H = 44.06 m

so the brick is 44.06 m tall
