In the figure, a ball is thrown leftward from the left edge of the roof, at height habove the ground. The ball hits the ground 2.10 s later, at distance d - 30.0 m from the building and at angle 8 - 64.0° with the horizontal. (a) Find h. (Hint: One way is to reverse the motion, as if on videotape.) What are the (b) magnitude and (c) angle relative to the horizontal of the velocity at which the ball...

Chapter 18, Problem 53 Your answer is partially correct. Try again. A small plastic ball of mass 5.44 x 10-3 kg and charge +0.120H'C is suspended from an insulating thread and hangs between the plates of a capacitor (see the drawing). The ball is in equilibrium, with the thread making an angle of 30.00 with respect to the vertical. The area of each plate is 0.01465 m2. What is the magnitude of the charge on each plate? 30.0 Number T3e-8...

In the figure here, a ball is thrown up onto a roof, landing
4.30 s later at height h = 20.0 m above the release level.
The ball's path just before landing is angled at θ = 68.0˚
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 velocity?...
