PHXI03:MOTION IN A STRAIGHT LINE

362155 Assertion :
A negative acceleration of a body can be associated with a 'speeding up' of the body.
Reason :
Increase in speed of a moving body is independent of its direction of motion.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
PHXI03:MOTION IN A STRAIGHT LINE

362156 The velocity of a particle at an instant is \(10\,m/s\). After 5 sec, the velocity of the particle is \(20\,m/s\). Find the velocity at 3 seconds before the instant when velocity of a particle is \(10\,m/s\)

1 \(8\,m/s\)
2 \(4\,m/s\)
3 \(6\,m/s\)
4 \(7\,m/s\)
PHXI03:MOTION IN A STRAIGHT LINE

362157 A body travels for \(12\,\sec \) starting from rest with constant acceleration. If it travels distance \({S_1},{S_2}\,{\mathop{\rm and}\nolimits} \,{S_3}\) in the first four seconds, second four seconds and next four seconds respectively the relation between \({S_1},{S_2}\,{\mathop{\rm and}\nolimits} \,{S_3}\) is

1 \({S_1} = \frac{1}{5}{S_2} = \frac{1}{3}{S_3}\)
2 \(5{S_1} = 3{S_2} = {S_3}\)
3 \({S_1} = \frac{1}{3}{S_2} = \frac{1}{5}{S_3}\)
4 \({S_1} = {S_2} = {S_3}\)
