An athlete does not come to rest immediately after crossing the winning line due to the

$Assertion$ : The driver in a vehicle moving with a constant speed on a straight road is an inertial frame of reference.
$Reason$ : $A$ reference frame in which Newton's laws of motion are applicable is non-inertial.

An astronaut accidentally gets separated from his small spaceship accelerating in interstellar space at a constant rate of $100 \; m/s^2$. What is the acceleration of the astronaut the instant after he is outside the spaceship (in $; m/s^2$)? (Assume that there are no nearby stars to exert gravitational force on him.)

When a car at high speed makes a sharp turn,the driver in the car tends to get thrown in the direction opposite to that of the turn. This is due to which property?

When a body is at rest or in uniform motion,no force acts on it. Is this statement true or false?
