Hide Time Rem 9 An airplane is dropping bales of hay to cattle stranded in a blizzard on the Great Plains. The pilot releases the bales at 180 m above the level ground when the plane is flying at 80.0 m/s 45.0° above the horizontal. Part A How far in front of the cattle should the pilot release the hay so that the bales will land at the point where the cattle are stranded?

Select one: a. R A golf ball is hit resulting in a velocity of v = 15.1 m/s @ 34.5° above the horizontal, as shown in the figure above. A wall which is 10.0 m high is located a distance of 18.9 m from the point at which the ball is launched. How long does it take for the ball to strike the wall? b. C. d. 7.59 s 1.23 s 1.52 s 0 2.21 s vo. 1 H Į

Can you solve the problems and show steps? Thanks.

Please provide the correct answer

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 golf ball is hit off the ground with a speed of 34.0 m/s at a 56.0° angle with the horizontal. If the a. How high (in meters) does the ball rise? b. If the ball lands on the ground at the same height that it was hit, how much time does the ball spend in the air? c. How many meters away does the ball land?

On a hot summer day, a young girl swings on a rope above the local swimming hole (Figure 1). When she lets go of the rope her initial velocity is 2.10 m/s at an angle of 35.0 ° above the horizontal. You may want to review (Pages 99 - 101). Part A If she is in flight for 0.611 S, how high above the water was she when she let go of the rope? ? h = Im

You buy a plastic dart gun, and being a clever physics student you decide to do a quick calculation to find its maximum horizontal range. You shoot the gun straight up, and it takes 4.0 ss for the dart to land back at the barrel.     Part A What is the maximum horizontal range of your gun?

3. Penny drops a leaf into the water which runs east downstream. She measures the distance the leaf travels as 3.0 meters in 9.0 seconds. Penny then swims across the river, orienting herself perpendicular to the water, and lets the river current carry her downstream. She swims across the 57 m wide river in 47 seconds. a. Sketch the overall vectors of the velocities of the person to the water, the water to the ground and the person to the ground. Write the equation for the velocity of the person relative to the ground with the appropriate subscripts b. Determine the velocity of the water in the river relative to the ground. c. How far downstream will Olaf drift?" d. Determine the velocity of the person relative to the water (with direction) e. Determine the velocity of the person relative to the ground (with direction).

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?
