A particle moves in straight line. Its position is given by x=2+5t-3t². Find the ratio of initial velocity and initial acceleration.

As shown in the figure a particle is released from P. It reachet at Q point  at time t₁ and reaches at point R at time t₂ so = ……

particles A and B are released from the same height at an interval of 2 S. After some time t the distance between A and B is 100m. Caleulate time t.

Given graph shows relation between position (X)→ time (t) Find the correct graph of velocity→ time

Here are displacement → time graphs of particle A and B .if V_A and V_B are velocities of the particles respectively, then  =……

Given graph shows relation between position and time. Find correct graph of acceleration → time
