You are walking around your neighborhood and you see a child on top of a roof of a building kick a soccer ball. The soccer ball is kicked at 33° from the edge of the building with an initial velocity of 19 m/s and lands 55 meters away from the wall. How tall, in meters, is the building that the child is standing on? y m 20

A skier traveling horizontally at 7.00 m/s shoots off a vertical cliff. Moments later she hits horizontal snow again with a velocity at an angle of 55 degrees below the horizontal. A. Find her velocity as she hits the snow? B. For how long was she in the air? C. How far did she land from the foot of the cliff?

Jack and Jill ran up the hill at 2.9 m/s. The horizontal component of Jill's velocity vector was 2.5 m/s a. What was the angle of the hill? b.

A baseball is hit with an initial velocity of 20 m/s at an angle of 22 degrees above the horizontal and at an initial height of .9 m. a. How high will the baseball go? b. How far will the baseball go when it hits the ground?

An archer fish spies a meal of a grasshopper sitting on a long stalk of grass at the edge of the pond in which he is swimming. The fish is to successfully spit at and strike the grasshopper, which is 0.200 m away horizontally and 0.745 m above his mouth.   a. What is the minimum speed at which the archer fish must spit? answer in m/s b. What angle (in degrees) above the horizontal must he spit? answer in degrees

Two spheres are launched horizontally from a 1.2 mm -high table. Sphere AA is launched with an initial speed of 4.5 m/sm/s . Sphere BB is launched with an initial speed of 2.5 m/sm/s . A. What is the time for the sphere AA to hit the floor? Express your answer using two significant figures.   B. What is the time for the sphere BB to hit the floor? Express your answer using two significant figures.

A cannonball is fired from a height of 25 m above ground level, with an initial speed of 22.36 m/s and at an angle of 63.4⁰ above the horizontal. The cannonball lands at ground level. a. How long was the ball in the air (the “hang time")? b. How far does the cannonball travel horizontally? c. What is the final speed of the cannonball just before making contact with the ground?

A secret agent skis off a slope inclined at θ = 28.3 degrees below horizontal at a speed of v0 = 17.4 m/s. He must clear a gorge, and the slope on the other side of the gorge is h = 11.9 m below the edge of the upper slope. a.)What is the maximum width, w, of the gorge (in meters) so that the agent clears it?

At the beginning of a 3.0-h plane trip, you are traveling due north at 192 km/h. At the end, you are traveling 239 km/h in the northwest direction (45° west of north). a. Which of the following are the initial and final velocity vectors? SEE ATTACHMENTS b. Find the magnitude of the change in velocity. anser in km/h c. Find the change in direction of your velocity. Enter the angle in degrees where negative indicates north of west and positive indicates south of west. answer in degrees d. What is the magnitude of your average acceleration during the trip? answer in km/h^2
