Phys 202 Quiz 2 Name: Three identical particies are shown below. E a. 1. Find the net force (magnitude and direction) on each particle. (ans: 2.66Ne110: 1SIN@13.1: 2.90N@259 aned Alas Quiz 1 PHYS 2 1. A stone is thrown upward from a building with a speed of 24.0m/s at 65.0r and lands 60.6m from the base of building in the x-direction. a. How long is the stone in the air?(ans: 5.98s) b. Solve for the height of the building. (ans: 45.0m) se-Ins A 5.00kg weight hangs from two cables connected to a ceiling a. Draw a free body diagram for the weight. b. Solve for the force on each cables. (ans: 35.9N, 25.AN) 2. 45/60°Explanation / Answer
1)
initial speed , u = 24 m/s
theta = 65 degree
x = 60.6 m
a) let the time of stone is air is t
t = x/(u * cos(theta))
t = 60.6/(24 * cos(65 degree))
t = 5.97 s
the time taken is 5.97 s
b)
for the height of building
height of building = 24 * sin(65 degree) * 5.97 - 0.50 * 9.8 * 5.97^2
height of building = -44.8 m
height of building = 44.8 m
the height of building is 44.8 m
