An object of mass 500 g, initially at rest, is acted upon by a variable force whose X-component varies with X in the manner shown. The velocities of the object at the points X = 8 m and X = 12 m, would have the respective values of (nearly)
Text Solution
Verified by ExpertsThe correct answer is:
C
Area of curve from x = 0 to x = 8
= (20 × 5) + 10(c) = 130
Work energy theorem
130 = 
× 
× 
So v 1 = 
23 m/sec
Now we can observe that total are from x = 8 to x = 12 is negative. So velocity at x = 12 will be less than
23 m/sec.
