1. Homework Statement
A object is projected with a velocity of 100 m/s at an elevations 30 degrees from a tower 150m high.
a) Time of flight
b) The horizontal distance from the tower at which the stone strikes that ground.
c) The magnitude and the direction of the velocity of the stone striking the ground.
2. Homework Equations
x=ut+0.5at^2
Trigonometry
v^2 = u^2 + 2ax
3. The Attempt at a Solution
a)
=>v=u+at
50.2=100 10t
t1= 5.02s
t2 = 5.02s
t3=?
Am I on the right track at all?
