Question

Q 14/90 A particle of 2 kg mass is moving in
straight line, along x-axis. Its position is given by x(t)
= 4t2 - 3t, where t is in second. Select incorrect
option.
Rate of change of position is minimum at
t = 0.375 s
Average velocity of particle will be zero
from
t = 0 to t = 0.75 s
Acceleration of particle is time independent
Velocity of particle will be zero at t = 1.50 s​

Answer 1

Answer:

Option D is incorrect because velocity at 1.50sec would be (please refer to the above attachment)
