Step 1
- Angle of projection, \(\theta = 30^\circ\) - Horizontal distance to the building, \(d = 20 \, \text{m}\) - Vertical height of the building, \(h = 5 \, \text{m}\) - Acceleration due to gravity, \(g = 9.8 \, \text{m/s}^2\) Show more…

A ball is thrown upward at an angle of $30^{\circ}$ to the horizontal and lands on the top edge of a building that is $20 \mathrm{~m}$ away. The top edge is $5.0 \mathrm{~m}$ above the throwing point. How fast was the ball thrown?
A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 8.00 $\mathrm{m} / \mathrm{s}$ at an angle of $20.0^{\circ}$ below the horizontal. It strikes the ground 3.00 s later. (a) How far horizontally from the base of the building does the ball strike the ground? (b) Find the height from which the ball was thrown. (c) How long does it take the ball to reach a point 10.0 $\mathrm{m}$ below the level of launching?
