Let u = initial velocity of the first particle V1, V2 ard the velocities of first and second particle respectively θ1 & θ2 are tbe angles made by the first & second particle respectively with the original direction of U Let u = initial velocity of the first particle V1, V2 ard the velocities of first and second particle respectively Equting conservation of momentum in the direction of initial direction of U, & perpendicular to it, one get, mU + 0 = m V1 cos θ1+ m cosθ2............. i 0 + 0 = m V1 sinθ1 + m V2 sinθ2.............ii For elastic collision kinetic energy is also conserved. Equating i initial & final kinetic energener, (1/2)mu2 + 0 = (1/2) mV12 + (1/2) m V22.. Iii & adding eqn. i, ii, we get U2 =V12 + V22 + 2 V1V2 cos (θ1 + θ2 ) This equation will be identical to eqn. iii, only when ( θ1 +θ2 ) = 90 degree. + read less

A body is initially at rest. It undergoes one-dimensional motion with constant acceleration. The power delivered to it at time t is proportional to (i) t1/2 (ii) t (iii) t3/2 (iv) t2
Power=FVCosA=ma.(u+at)Cos0=ma.(0+at).1=ma^2.t. Which is propotionalp to t. So correct answer (ii) t.

Why does a swimmer push the water backwards?
According to newton's 3rd law of motion in each and every action there is an equal and opposite force. So if he push the water backwards then according to the above principle or law he will be able to move forward.

A lift is accelerated upward. Will the apparent weight of a person inside the lift increase, decrease or remain the same relative to its real weight? If the lift is going with uniform speed, then?
Thd apparent weight of the person will increase. When in uniform speed then acceleration is zero, so no change in weight.
