Q- A bus is running along a highway at a speed of v₁ =16 ms^-1. A man is at a distance a = 40m from the highway and at a distance b = 196 m from the bus. In what direction should the man run to reach any point on the highway at the same time as the bus or before? The man can run at a speed of v₂=4 ms^-1.

Solution:

Q- An object of mass m starts from rest and slides a distance d down a frictionless incline of angle θ. While sliding, it contacts an unstressed spring of negligible massand force constant k.  The object slides an additional distance x as it is brought momentarily to rest by compression of the spring. Find the initial separation d between object and spring.
