Question

Problem 11.16 Part A A 1.3 kg particle moving along the r-axis experiences What is its velocity at z = 2m2 Express your answer to two significant figures and include the appropriate units. the force shown in the figure(Figure 1) The particle's velocity is 5 2 m/s at z = 0 m Value Units Subrnit My Answers Give Up Part B What is its velocity at z=4m? Express your answer to two significant figures and include the appropriate units 0 Value Units Submit My Answers Give Up F, (N) Provide Feedback 10 -x (m) 10

Explanation / Answer

Work done = change in KE

(A) W = 10 x 2 / 2 = 10 J

10 = 1.3 (v^2 - 5.2^2)/ 2

v = 6.51 m/s

(B) W = 10 x 2/2 - 10 x 2 / 2 = 0

v = v0 = 5.3 m/s
