Express all answers in significant figures and scientific notation. A man was standing on one side of the roof of a building 145 meter above the ground and shot a projectile with an initial speed of 53 m/s at an angle of 30.0 degrees with the horizontal. Find: a) the time ( seconds) it took the projectile to hit the ground b) how far (meter) away from the base of the building did the projectile land? c) Find the vertical and horizontal components of the velocity (m/s) d) what is its velocity in m/s
