A ball is thrown from an initial height of 3.2 m above the ground. Its initial velocity is 6.5 m/s at an angle of 22◦ above the horizontal. (a) How much time does the ball spend in the air? (b) How much time does it take for the ball to reach its maximum height? Take g = 9.81 m/s2
A ball is thrown from a rooftop with an initial downward velocity of magnitude v0 = 1.1 m/s. The rooftop is a distance above the ground, h = 46 m. In this problem use a coordinate system in which upwards is positive. Part (a) Find the vertical component of the velocity, Vfy, in meters per second, with which the ball hits the ground. Part (b) If we wanted the ball's final speed to be exactly 27.3 m/s from what height, hnew (in...
In the figure here, a ball is thrown up onto a roof, landing 3.80 s later at height h = 25.0 m above the release level.

What are the (b) magnitude and (c) angle (relative to the horizontal) of the ball's initial velocity? Number Unit Number Unit Number Unit
In the figure here, a ball is thrown up onto a roof, landing 3.10 s later at height h = 24.0 m above the release level. The ball's path just before landing is angled at θ = 56.0˚ with the roof. (a) Find the horizontal distance d it travels. (Hint: One way is to reverse the motion, as if it is on a video.) What are the (b) magnitude and (c) angle (relative to the horizontal) of the ball's initial...
