An arrow gains a momentum of 96.3 kg*m/s [W] in 0.700 s. Determine the magnitude and direction of the average unbalanced force that acted on the arrow. UT bysics 30 - Assignment 13. A high school football player hits and pushes a tackling dummy during practice. The following graph shows the amount of force that acts on the player. Note the negative value in the scale indicates the direction of the force.

Physics 30 - Assignment 1 b. If the 60 kg player is running forward at 7.0 m/s when she makes contact with the dummy, what is the player's velocity at the end of the 1.20 s impact?c. From 0.0 s to 0.1 s, what is happening to the acceleration of the player? The player is accelerating at a) an increasing rate in the forward direction b) a decreasing rate in the forward direction c) a decreasing rate in the backward direction d) an increasing rate in the backward direction d. From 0.1 s to 0.2 s, what is happening to the acceleration of the player? The player is accelerating at a) an increasing rate in the backward direction b) an increasing rate in the forward direction c) a decreasing rate in the forward direction d) a decreasing rate in the backward direction e. Identify the time interval where the net force negative. What does this indicate about the direction of the force
