Use g = 10 m/s/s. You push a 30 kg stationary box across a rough surface with a sideway force of 80 N in the positive direction over a time of 4 seconds. The coefficient of kinetic friction is 0.20. Let the direction to the right be positive. Required:
a. What is the contribution from the push force to the total impulse?
b. What is the contribution from the friction force to the total impulse?
c. What is the total impulse given to the box?
d. What is the final velocity of 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.
