Pumpkin Toss In Denver, children bring their old jack-o-lanterns to the top of a tower and compete for accuracy in hitting a target on the ground (FIGURE 4-21). Suppose that the tower is 9.0 m high and that the bull's-eye is a horizontal distance of 3.5 $\mathrm{m}$ from the launch point. If the pumpkin is thrown horizontally, what is the launch speed needed to hit the bull's-eye?

Step 1
0 \, m\), \(a = 9.81 \, m/s^2\) \[9.0 = 0 \times t + \frac{1}{2} \times 9.81 \times t^2\] \[4.905t^2 = 9.0\] \[t^2 = \frac{9.0}{4.905}\] \[t = \sqrt{\frac{9.0}{4.905}}\] \[t \approx 1.355 \, s\] Show more…

In Denver, children bring their old jack-olanterns to the top of a tower and compete for accuracy in hitting a target on the ground (Figure $4-15) .$ Suppose that the tower is $9.0 \mathrm{m}$ high and that the bull's-eye is a horizontal distance of $3.5 \mathrm{m}$ from the launch point. If the pumpkin is thrown horizontally, what is the launch speed needed to hit the bull's-eye?
(III) A toy rocket moving vertically upward passes by a 2.0 -m-high window whose sill is 8.0 $\mathrm{m}$ above the ground. The rocket takes 0.15 $\mathrm{s}$ to travel the 2.0 $\mathrm{m}$ height of the window. What was the launch speed of the rocket, and how high will it go? Assume the propellant is burned very quickly at blastoff.
