Coast Guard rescue swimmers are trained toleap from helicopters into the sea to save boaters in distress. Therescuers like to step off their helicopter when it is “ten and ten,”which means that it is ten feet above the water and moving forward horizontally at ten knots. What are (a) the speed and (b) thedirection of motion as a rescue swimmer enters the water following a ten and ten jump?
in Denver, children bring their old jack-o-lanterns to the top of a tower and compete for accuracy in hitting a target on the ground. Suppose that the tower is 9.0 mm high and that the bull's-eye is a horizontal distance of 3.5 mm from the launch point. If the pumpkin is thrown horizontally, what is the launch speed needed to hit the bull's-eye?
In Canadian football, after a touchdown the team has the opportunity to earn one more point by kicking the ball over the bar between the goal posts. The bar is 10.0 ftft above the ground, and the ball is kicked from ground level, 36.0 ftft horizontally from the bar in (Figure 1). Football regulations are stated in English units, but convert to SI units for this problem. If the ball is kicked at 39.0 ∘∘ above the horizontal, what must its initial speed be if it is just to clear the bar? Express your answer in m/sm/s
the leprechaun in the shamrock patch was named O'Malley and since he was disrupted from sitting in his patch he decided to go off and play a round of his favorite sport in where leprechaun kick a gold coin from a tee into a post 317m away. if he kicked the coin at an angle of 60 degree at a velocity of 60 m/s how high was the arch of the rainbow created by the trajectory? how long did it take to get to the pot? the officials in dublin decided to add a goal post to "kick O coin" 300 meters away and so many 33 meters high. would O'Malley's kick have cleared this goal post?
A volcano shoots a lava bomb straight upward. Does the displacement of the lava bomb depend on (a) your choice of origin foryour coordinate system, or (b) your choice of a positive direction?Explain in each case.
An enemy ship is on the east side of a mountain island, as shown in the figure. The enemy ship has maneuvered to within d1 = 2077 m of the h = 1940 m high mountain peak and can shoot projectiles with an initial speed of vi = 244 m/s. If the western shoreline is horizontally d2 = 273 m from the peak, what are the distances from the western shore at which a ship can be safe from the bombardment of the enemy ship?
A rocket is launched at an angle of 53.0 above the horizontal with an initial speed of 100. m/s. The rocket moves for 3.00 s along its initial line of motion with an acceleration of 30.0 m/s2. At this time, its engines fail and the rocket proceeds to move as a projectile. Find (a) the maximum altitude reached by the rocket, (b) its total time of flight, and (c) its horizontal range.

A commuter airplane starts from ar. airport and takes the route shown in Figure P3.19. The plane first flies to city A, located 175 km away in a direction 30.0 north of east. Next, it flies for 150 km 20.0 west of north, to city B. Finally, the plane flies 190 km due west, to city C. Find the location of city C relative to the location of the starling point. Figure P3.19
A ball is shot from the top of a building with an initial velocity of 18 m/s at an angle θ = 43° above the horizontal. If a nearby building is the same height and 61 m away, how far below the top of the building will the ball strike the nearby building? ( Choose upward as the positive y-direction and express the displacement with the sign of the result, which must be in units of meters and include 1 digit after the decimal point. Maximum of 5% of error is accepted in your answer. Take g=9.80 m/s2.)
William Tell is said to have shot an apple off his son’s head with an arrow. If the arrow was shot with an initial speed of 50.0 m/s and the boy was 26.0 m away, at what launch angle above the horizontal did Bill aim the arrow? (Assume that the arrow and apple are initially at the same height above the ground. Hint: sin2θ = 2sinθcosθ)
In U.S. football, after a touchdown the team has the opportunity to earn one more point by kicking the ball over the bar between the goal posts. The bar is 10.0 ft above the ground, and the ball is kicked from ground level, 36.0 ft horizontally from the bar (the figure (Figure 1)). Football regulations are stated in English units, but convert to SI units for this problem. If the ball is kicked at 37 ∘ above the horizontal, what must its initial speed be if it to just clear the bar? Express your answer in m/s.
