Questions
A smooth curved surface of height 10m is ended horizontally. A spring of force constant is fixed at the horizontal end as shown in figure. When an object of mass 10 g is released from the top, it travels along the curved path and collides with the spring. Then, the maximum compression in the spring is (Take, )
detailed solution
Correct option is B
Let the maximum compression in the spring be x. From law of conservation of energy, mgh=12kx2 10×10-3×10×10=12×200×x2⇒ x2=10×10-3=10-2⇒ x=1100=110m=0.1mThus, compression in the spring is 0.1m.Talk to our academic expert!
