A child slides down a frictionless 3.0-m-long playground slide tilted upward at an angle of 40°. At the end of the slide, there is an additional section that curves so that the child is launched off the end of the slide horizontally.
a. How fast is the child moving at the bottom of the slide?
b. If the end of the slide is 0.40 m above the ground, how far from the end does she land?

- A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of vi = 18.0 m/s. The cliff is h = 50.0 m above a body of water as shown in Figure P4.13. (a) What are the coordinates of the initial position of the stone? (b) What are the components of the initial velocity of the stone? (c) What is the appropriate analysis model for the vertical motion of the stone? (d) What is the appropriate analysis model for the horizontal motion of the stone? (e) Write symbolic equations for the x and y components of the velocity of the stone as a function of time. (f) Write symbolic equations for the position of the stone as a function of time. (g) How long after being released does the stone strike the water below the cliff? (h) With what speed and angle of impact does the stone land?

A student wants to toss a textbook to his roomate who is leaning out of a window directly above him. He throws the book upwards with an initial velocity of 8.0 m/s. The roomate catches it while it is travelling at 3.0 m/s upward. A. How long was the book in the air? B. How far vertically did the book travel? C. Redo the problem, and have the roomate catch the book as it is travelling 3.0 m/s downward. What is the time and displacement now? 3. A man is standing on the edge of a 20.0 m high cliff. He throws a rock vertically with an initial velocity of 10.0 m/s A. How high does the rock go? (Remember that at its max height v = 0 m/s) B. How long does it take to reach it max height?arrow_forward
- A roof worker loses his grip on his box of tools while working on a tall house. His box slides down the roof. The roof is angled at 29 degrees with the horizontal. The roof is made of a frictionless material. The box travels 5 m down the roof and then leaves the edge of it 12 m above the ground. a). Figure out the box's velocity as it leaves the house's roof? b). How far from the base of the house does the box hit the ground? c). By how much does the box clear the yard fence which is 1.8m tall and located 6.7m away from the base of the house?
