You and a friend try to move a 50.0 kg box over a smooth floor (no friction). you push down and right with a force 30.0 n, at angle of 20 degrees below the horizontal. your friend ties a rope to the front of the box and pulls with a 25.0 n force, at an angle 30 degrees above the horizontal. what is the acceleration of the box in the horizontal direction? assuming the box does not move in the vertical direction, what is the normal force on the box?

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 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. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) 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. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
