Question

All three following appreciate it!!! o5/8 points 1 Previous Answers M14 5.8.033 Notes Ask Your Teaches In the dark in outer space, you observe a glowing ball of known mass 4.2 kg moving in the xy plane at constant speed in a circle of radius 9 m, with the center of the circle at the origin ( m). You can't see what's making it move in a circle. At time t0 the ball is at location 9, 0, 0 > m and has velocitym/s. (a) On your own paper draw a diagram of the situation, showing the circle, and showing the position and velocity of the ball at time t-O. The diagram will help you analyze the situation. Use letters a-j to answer questions about directions (+x to the right, ty up):8 / zero magnitude (b) At time t 0, what is the direction of the vector p? e (c) At time t O, what are the magnitude and direction of dipl p, the parallel component of dp magnitude o dt dt kg·m/s/s

Explanation / Answer

e) -i (towards -x axis)

f) Fnet = m*v^2/R

= 4.2*80^2/9

= 156.8 N

g) F2 = < -(1194 + 156.8), +2688 >

= < -1350.8, 2688, 0 > N
