projectile is launched upward at an initial slope of 4 vertical and 3 horizontal. The ground  sloped downward such that the projectile hits the ground at a point 2 m lower than that of the origin.  The maximum height of the flight is attained at a horizontal distance of 8 m away from origin. a. What is the initial velocity of the projectile? b. What is the total

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.

An Alaskan rescue plane drops a package of emergency rations to a stranded party of explorers. If the plane is traveling east at 40 m/s and is 100 meters above the ground:   a.Using the release point as the origin, find the time it takes for the package to reach the ground once released.   b.How far east of the release point does the package strike the ground? Also, What is the speed of the package as it hits the ground?   c.With what angle (below the horizontal) does the pack strike the ground? Please show work for all of the parts.

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

Part A and B on paper

Flight of a golf ball A golf ball is driven down a horizontal fairway withan initial speed of 55 m/s at an initial angle of 25° (from a tee with negligible height). Neglect all forces except gravity, and assume the ball’s trajectory lies in a plane.a. When the ball first touches the ground, how far has it traveled horizontally and how long has it been in the air?b. What is the maximum height of the ball?c. At what angles should the ball be hit to reach a green that is 300 m from the tee?

A projectile is launched at an angle of 30°to the horizontal from 6.5 ft above the ground at an initial speed of 100​ft/sec. Assume the​ x-axis is​ horizontal, the positive​ y-axis is vertical​ (opposite g), the ground is​ horizontal, and only the gravitational force acts on the object. a. Find the velocity and position vectors for t≥0. b. Determine the time of flight and range of the object. c. Determine the maximum height of the object.

Whale sharks swim forward while ascending or descending. They swim along a straight-line path at a shallow angle as they move from the surface to deep water or from the depths to the surface. In one recorded dive, a shark started 50 m below the surface and swam at 0.85 m/s along a path tipped at a 13° angle above the horizontal until reaching the surface. a. What was the horizontal distance between the shark's starting and ending positions?

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 50° from the edge of the building with an initial velocity of 10 m/s and lands 20 meters away from the wall of the building. How long was the ball in the air? Group of answer choices A. 3.1 s B. 2.0 s C. 6.4 s D. 5.2 s
