- A projectile is launched from the top of the cliff of height h with initial velocity v0 and launch angle ? with respect to the horizontal. It later hits the ground. Derive an expression for the magnitude and direction angle of the velocity as the object hits the ground in terms of some or all of the variables given in the problem h, v0 , ?, and g.A student throws a water balloon at an initial angle θ = 23° above the horizontal with an initial speed v0 from a height h = 1.52 m. The target is located on the ground at a horizontal distance d = 7.5 m from the student’s feet. Assume that the balloon moves without air resistance. Use a Cartesian coordinate system with the origin at the balloon's initial position. In terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. Your answer should not include h.A student standing on a cliff that is a vertical height d = 8.0 m above the level ground throws a stone with velocity v0 = 17 m/s at an angle θ = 27 ° below horizontal. The stone moves without air resistance; use a Cartesian coordinate system with the origin at the stone's initial position. With what speed, vf in meters per second, does the stone strike the ground?
- A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of vo=18.5 m/s. the cliff is h=49.0 m above a flat, horizontal beach. what are the coordinates of the initial position of the stone and the components of the initial velocity?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 22.0° below the horizontal. It strikes the ground 5.00 s later.

If the wind imparts a constant horizontal deceleration of 3.9 ft/sec2, determine the values of r, r˙, r¨, θ, θ˙, and θ¨ when t = 1.18 sec. Take the r-coordinate to be measured from the origin.
- A projectile is thrown from the top of a cliff with an initial speed of 25 m/s at an angle of 600 up from the horizontal. If the projectile lands 100 m from the base of the cliff how tall is the cliff?An airplane undergoes the following displacements: First, it flies 66 km in a direction 30° east of north. Next, it flies 49 km due south. Finally, it flies 100 km 30° north of west. Using vector components, determine how far the airplane ends up from its starting point. A test rocket is fired straight up from rest with a net acceleration of 20.0 m/s2 upwards. After 4.00 seconds the motor turns off, but the rocket continues to coast upward with no appreciable air resistance (deaccelerating). What maximum elevation does the rocket reach during its flight H DELL O WOne of the tasks of the Mighty Hercules was to protect the town of Nemea from a lion. One day Hercules sees the lion 320 feet away. He strings his bow and lets an arrow fly. The arrow leaves his bow travelling at 210 feet per second from a height of 6 feet. He wants to hit the lion in the neck above the shoulders which is 4 feet off of the ground. determine the launch angle that will hit the Lion. Find the right angle.
