A) The best leaper in the animal kingdom is the puma, which can jump to a height of 3.7 m when leaving the ground at an angle of 45°. With what speed must the animal leave the ground to reach that height?  m/s = B) A brick is thrown upward from the top of a building at an angle of 20° to the horizontal and with an initial speed of 11 m/s. If the brick is in flight for 2.6 s, how tall is the building?  m =

A rock is thrown vertically upward with a speed of 13.0 m/sm/s from the roof of a building that is 70.0 mm above the ground. Assume free fall. What is the speed of the rock just before it strikes the ground? I will rate accordingly with multiple votes. Please do it correctly.

A brick is thrown upward from the top of a building at an angle of 15° to the horizontal and with an initial speed of 12 m/s. If the brick is in flight for 3.3 s, how tall is the building? m

A ball is thrown horizontally with a velocity of 5 m/s from the top of a tall cliff. Neglecting air drag, a) What is the speed of the ball 2 seconds later. b) What vertical distance has the ball fallen 2.0 seconds later? You must include a sketch to solve

A mischievous caracara sees a fisherman unscrew a shiny steel nut from a bolt on his ship while doing repairs in a harbor off the Falkland Islands. The fisherman watches helplessly as the bird picks up the nut and flies toward the shore. The bird flies due east at a constant speed of 5m/s and constant height of 11m . The bird flies directly over a person on the shoreline, dropping the nut at the instant they are above the person. Prepare: Once the nut has been released, in which directions does the acceleration vector have components along?

1b. A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v0 = 18.5 m/s. The cliff is h = 20.0 m above a flat, horizontal beach as shown in the figure. What are the components of the initial velocity? v0x =  ____m/s v0y =  ____m/s

A)  With what speed, in meters per second, does the stone strike the ground? vf=

Mature salmon swim upstream, returning to spawn at their birthplace. During the arduous trip they leap vertically upward over waterfalls as high as 3.31 m. With what minimum speed (in m/s) must a salmon launch itself into the air to clear a 3.31-m waterfall? in m/s

2. Niko accidently throws his cellphone out of an open window horizontally with a velocity of 4.5 m/s. Niko quickly looks out the window and notices a friend outside. The window is 8.5 m above the ground. How far away from the building should the friend stand to catch the cell phone at ground level?

A particle at rest undergoes an acceleration of 2.1 m/s2 to the right and 3.9 m/s2 up. a)What is its speed after 5 s in m/s? b)What is its direction with respect to the horizontal at this time? Answer between −180◦ and +180◦.
