Two particle of masses m and 2m are coliding elastically as given in figure. If V_(1) and V_(2) speed of particle just after collision then

A particle A of mass m initially at rest slides down a height of 1.25 m on a frictionless ramp, collides with and sticks to an identical particles B of mass m at rest as shown in the figure. Then, particles A and B together collide elastically with particle G of mass 2m at rest. The speed of particle G after the collision with combined body (A+B) would be (Take, g =10 ms^(-2))

consider a head on collision between two particles of masses m_1 and m_2 . The initial speeds of the particles are u_1 and u_2 in the same directioin. The collision starts at t=0 and the particles interact for a time inteval /_\t. Lduring the collision the speed o the first particle varies as v(t)=u_1+t//_\(v_1-u_1) Find the speed of the second particle as as function of time during the collision.

Blocks of masses m , 2m , 4m and 8m are arranged in a line on a frictionless floor . Another block of mass m , moving with speed v along the same line (see figure ) collides with mass m in perfectly inelastic manner. All the subsequent collisions are also perfectly inelastic. By the time the last block of mass 8 m starts moving the total energy loss is p% of the original energy . Value of 'p' is close to :

Two particles of masses m_1 and m_2 in projectile motion have velocities vecv_1 and vecv_2 respectively at time t=0. They collide at time t_0. Their velocities become vecv_1' and vecv_2' at time 2t_0 while still moving in air. The value of |(m_1vecv_1' + m_2vecv_2') - (m_1vecv_1 + m_2vecv_2)| is
