A bullet has a speed of 2000 ft/s as it leaves a rifle. If it fired horizontally from a cliff 24 ft above a lake, find the magnitude and direction of the bullet as it strikes the lake.

A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 8.10 m/s at an angle of 19.0° below the horizontal. It strikes the ground 5.00 s later. (a) How far horizontally from the base of the building does the ball strike the ground? m(b) Find the height from which the ball was thrown. m(c) How long does it take the ball to reach a point 10.0 m below the level of launching? s

A ball is kicked is aimed at a target 30 meters away, horizontally, and at 1.8 m vertically above the ground. It is kicked at an angle of 35 degrees with the ground.   What is the time, in seconds, for the ball to reach the target?

A projectile launched at 45° upwards from the ground takes 2.4 seconds to return to the ground. Approximately what speed was the projectile launched?

A boat that can travel at 2.50 m/s in still water is heading directly across a river that is flowing at a rate of 1.25 m/s, i.e., so that it will end up downstream. (a) What is the velocity of the boat as measured by a person standing on the shore? Give both the magnitude and the angle. (b) If the river is 175 m across, how long does it take the boat to cross the river and in this time how far down stream will the boat have traveled? (c) Provide a diagram of the situation.

A rocket is launched at ground level with an initial speed of 189 ft/s, at an angle of 34° above the horizontal. It strikes a mark above the ground 2.4 seconds later.What is the vertical distance, in feet, from where the rocket was launched to where it lands?

A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 7.70 m/s at an angle of 25.0° below the horizontal. It strikes the ground 5.00 s later. (a) How far horizontally from the base of the building does the ball strike the ground?m(b) Find the height from which the ball was thrown.m(c) How long does it take the ball to reach a point 10.0 m below the level of launching?s

(a) From a balcony a child fires a toy arrow down to the ground below. The arrow has initial speed 12 m/s and is aimed at an angle of 30° below the horizontal. The arrow takes 1.2 seconds to hit the ground. (i) Calculate the initial horizontal (✰) and vertical (ŷ) velocity components of the arrow. (ii) Calculate the height of the balcony. (b) A projectile is launched with an initial speed of 75 m/s at an angle of 52° above the horizontal. If it lands at the same height from which it was launched, calculate how long the projectile remains in the air.

A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 8.60 m/s at an angle of 18.0° below the horizontal. It strikes the ground 6.00 s later. (a) How far horizontally from the base of the building does the ball strike the ground? m (b) Find the height from which the ball was thrown. m (c) How long does it take the ball to reach a point 10.0 m below the level of launching?

A cannon ball is fired with a velocity of 300 m/s at an angle of 10° with respect to the ground. How long will the cannonball fly through the air? (Ignore the height of the cannon and assume the cannon ball is fired from ground level.)
