Whirl a rock at the end of a string and it follows a circular path. If the string breaks, the tendency of the rock is to follow a straight-line path. This is explained by:_______.
a) its velocity.
b) its constant force.
c) its inertia.
d) its greater acceleration.

When the rock tied at the end of the string and rotated the rock has two accelerations acting on it. One is tangential acceleration and another one is radial acceleration.

The rock has that tendency to move tangential but due to centripetal force, it is rotating in a circular path.

But when the string breaks the rock will move in a straight path.

This is because of the inertia because rock tendency is to be in a straight path but due to external force it was moving in a circular path but when the string breaks it moves in a straight line.
