A projectile is fired horizontally from a gun that is 45.0 m above flat ground, emerging from the gun with a speed of 250 . At what horizontal distance from the firing | S point does it strike 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 0.335 m above his mouth. What angle (in degrees) above the horizontal must he spit?

A clif with an angled summit 900 m above the valley foor is a popular jumping of point for base jumpers.One particular base jumper gets a running start and runs of the side of the clif with a velocity of 4.00 m/sat an angle that is 25.0◦ below the horizontal, as shown.(a) How long is the base jumper in the air before she opens her parachute 150 m above the valley foor?(b) How far (horizontally) is she away from the clif?

From the window of a building, a ball is tossed from a height yo above the ground with an initial velocity of 7.50 m/s and angle of 21.0° below the horizontal. It strikes the ground 6.00 s later. (a) If the base of the building is taken to be the origin of the coordinates, with upward the positive y-direction, what are the initial coordinates of the ball? (Use the following as necessary: yo: Assume SI units. Do not substitute numerical values; use variables only.) X; = Y = (b) With the positive x-direction chosen to be out the window, find the x- and y-components of the initial velocity. Vi, x Vi, y = m/s %3D %3D m/s (c) Find the equations for the x- and y-components of the position as functions of time. (Use the following as necessary: yo and t. Assume SI units.)

An archer shoots an arrow at a 74.0 m distant target; the bull's-eye of the target is at same height as the release height of the arrow. (a) At what angle in degrees must the arrow be released to hit the bull's-eye if its initial speed is 37.0 m/s?

A projectile 10.0 above ground is fired with an initial speed of 12.0 m/s and an angle of 60.00above horizontal. Find (a) how long is the projectile in air? (b) how far does the projectile travel before hitting the ground? (c) the maximum height above ground reached by the projectile. (d) the final speed of the projectile just before it hits the ground.

If the cannon is on ground level, (delta y = 0), how far downrange will the projectile land? vi = 19 m/s, degree 45 (above the horizontal, pointing upward) What is the vi x = ? , what is the vi y = ?

Physics A baseball player hits a home run over the left-field fence, which is 104 m from home plate. The ball is hit at a point 1.02 m directly above home plate, with an initial velocity directed 31.5° above the horizontal. By what distance does the baseball clear the 3.00 m high fence, if it passes over it 3.10 s after being hit?
