A 10-kg ball is launched at ground level with an initial speed v0 = 15 m/s, at an angle θ = 31° with the horizontal. Air resistance is negligible.
How far from the launching point does the ball touch the ground again, in m? (This distance is called the range of the motion.)

A small, spring-loaded cannon launches a golf ball from level ground with an initial speed vi at an angle θi with the horizontal. The golf ball lands a horizontal distance R from its launch point. The highest point the golf ball reaches during its flight is a distance R/12 above the ground. In terms of R and g, find the following. (You may ignore air resistance.) (a) the time interval during which the golf ball is in motion t =...
A rocket is fired at an initial speed v0 = 141.0 m/s from ground level, at an angle θ = 33 degrees above the horizontal. Ignore air resistance. The magnitude of the gravitational acceleration is 9.8 m/s2. Choose the RIGHT as positive x-direction. Choose UPWARD as psotitive y-direction. Keep 2 decimal places in all answers (a) Find v0x, the x component of the initial velocity (in m/s) (b) Find v0y, the y component of the initial velocity (in m/s) (c)...

A ball is launched from the ground toward a tall wall of a building at initial speed v0 = 24 m/s at an angle of 39 degrees relative to the horizontal. The wall is at a distance of 32 m from the launch point. How far above the launch point does the ball hit the wall? Your answer should be in meters, but enter only the numerical part in the answer box.
