1 Q Advanced Level The displacement x of a particle moving along axis varies with time asx 2F 38 m where t is in seconds then 1 The particle retums to its initial position after The particle comes to rest at t Initial velocity of particle is zero Maximum velocity in positive x direction is m s A particle moves in a straight line under an acceleration varying linearly with time Its velocity time graph is shown in figure Then v m s 37 45 1 The particle comes to rest at t 7s 2 The initial velocity of particle is 1 m s 3 Maximum velocity of particle is 2 m s 4 The acceleration of particle is zero at t 3 s A particle starts from rest at x and acceleration varies with X as shown in the figure Then a m s que 2010 r x m 1 The particle comes to rest at x 20 m Maximum velocity in positive x direction is 4 6 m s Velocity at x 10 m is 60 m s Distance covered by particle till it returns to initial position is 80 m Py wo stones are thrown vertically upwards simultaneously from the same point on the ground with velocities y 40 m s and topg Motion in a Straight Line 119 relative separation between stones v v relative velocity of two stones a a relative acceleration of two stones 1 2 0 a V V os G y y O agan The acceleration a of a particle moving in a straight line varies with velocity v as a 1 v m s where v is in m s If initially the particle was at rest then poy Per Maximum velocity of the particle will be 1 m s 2 Maximum acceleration is 1 m s 3 The particle will finally come to rest Velocity of particle at t n2 s is 13A ball is projected vertically upwards from ground with velocity v 24 m s Assume the acreside produces a constant retardation of 2 mis meh g 10m s 1 The maximum height attained is 288 m 2 Time of ascent is more than time mvs
