Por question numbers 1-2, refer to figure 20. 1. If two groups in the game are exerting unequal and opposite forces on the ground, will the rope move?
2. Will the net force be equal to zero?
3. To what direction does the rope move?

For question numbers 4-6, refer to figure 21.

4. Are the forces acting on the chandelier unbalanced?
5. What force can cause the chandelier to fall?
6. What type of force is your answer in number 4?

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

Does anyone have the answers to online physics course plato course physics, semester a v3.0

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.
