Question

6.
A student is standing at a distance of 50 metres from the bus. As soon as the bus begins its motion with
an acceleration of 1ms the student starts running towards the bus with a uniform velocityy.
Assuming the motion to be along a straight road, Find the relative acceleration (In m/s )of the
student with respect to the bus. (Bus is heading in the positive direction)
(A) zero
(B)1
(C)-1
(D) 2​

Answer 1

I think the answer is (D) 2

Answer 2

Answer:

(C)-1

Explanation:

since, the student is running with a uniform velocity, its acceleration will be zero, why???

Final and initial velocities are same.

Given that, bus acceleration's 1 m/s²

Therefore, relative acceleration with respect of that bus = 0 – ( +1 ) ( Since, the bus's heading towards positive direction)

= –1
