Question

A collar is resting on a horizontal rod without friction. This collar is moved 0.1m to the right and released. What speed will it reach when it goes back to its original position?

k 200 N/m m = 5kg 400 mm 400 mm k -200 N/m 10-300 mm 400 mm

Answer 1

Intial extension in options = 100 mm 0.1 m when it is displaced towords right log 0.1 m By energy at A & B 1/2 k times (0.1)^2 + 1/2 k (0.412 - 0.3)^2 1/2 k times (0.1)^2 + 1/2 mv^2 mv^2 = 2.5227 v = 0.71 m/s speed at original will be 0.71 m/s
