You throw a rock with an initial speed of 30 m/s and an angle of 50 degrees with respect to the vertical. The field you are on is however not horizontal but is inclined by an angle of 10 degrees with respect to and above the horizontal. Choose a coordinate system whose origin is located where the rock is thrown, and a rotated system such that the positive y axis is positive at an angle of 100 degrees measured counterclockwise...
A student throws a water balloon with speed vo from a height h = 1.52 m at an angle θ=39° above the horizontal toward a target on the ground.
A student throws a water balloon with speed vo from a height h = 1.52 m at an angle θ=39° above the horizontal toward a target on the ground. The target is located 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. Part (a) what is the position vector, Rtarget that originates from the balloon's original position and...
