Suppose a man is playing golf, he hits a ball with a velocity of 45 m/sec at an angle of 20 degrees to the horizontal. The projectile model can be used to answer some questions about what will happen to the ball later during its flight. Answer the ff: a. Where will the ball be 2 seconds later? b. What is the greatest height the ball reach? c. How long will the ball be in the air? How far will it travel horizontally before it hits the ground?

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?b. What was the total distance that the shark swam?c. How much time did this motion take?

6. man stands on the roof of a 50 m tall building and throws a ball with a speed of 25 m/s at 40° above the horizontal. If we ignore the air resistance; a. Find the vertical and horizontal components of the ball's initial velocity. b. Find the maximum height above the ground that the ball reaches. c. Find the ball velocity (in unit vector nutation) just before it strikes the ground. d. At what horizontal distance from the edge of the building does the ball strikes the ground? e. What is the vertical acceleration of the ball at the maximum height? a. Vox 19.15 m/s Voy 16.07 m/s b. y = 50+ 13.18 = 63.18 m e. c. Vx = Vox = 19.15 m/s v=vxî + vyĵ = 19.15î — 35.18ĵ d. x = 100.16 m ay = -9.8 m/s² Vy = -35.18 m S 0000000000 00 DO 00 00 vo 40° 50 m

A ball is thrown horizontally from a height of 1 m and lands 5 m away. a. What is the time of flight of the ball? b. What is the initial velocity of the ball?

A javelin thrower standing at rest holds the center of the javelin behind her head, then accelerates it through a distance of 70cm as she throws. She releases the javelin 2.0m above the ground traveling at an angle of 30° above the horizontal. In this throw, the javelin hits the ground 62m away. a. What was the acceleration of the javelin during the throw? Assume that it has a constant acceleration. b. What is the speed of the javelin as it leaves the hand of the thrower? c. What is the maximum height reached by the javelin? O 10.5m 9.8m O 8.5m O 7.0m

5. A ball is thrown horizontally by a pitcher from a height of 1 m and lands 18.4 m away on the ground behind home plate. a). Draw a simplified sketch of only the ball, it's release height, trajectory, and landing point. b) What is the time of flight of the ball? c). What is the initial velocity of the ball? 7. A water park is designing a new water slide that finishes with the rider flying horizontally off the bottom of the slide. The slide is designed to end 1.2 m above the water level, and the average rider is estimated to leave the bottom of the slide at 25 m/s. a). Draw a sketch of the scenario showing the trajectory of the rider from the bottom of the slide to the water. b) Determine how far will the rider fly through the air (horizontally) before hitting the water?

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?

Part A and B on paper

During a football game Aiden kicks a ball from the ground at the 30-yard line. He gives the ball an initial speed of 20 meters per second, at an initial angle of 36.9 degrees. a. One second after the kick how high is the ball above the ground measured in feet? b. How far away will the ball land on the ground measured in yards?

Pls help ASAP. Pls give directions and magnitude in each question.
