What is the law of moving a body of mass 2kg?

A body of mass 2kg travels according to the law x(t) = pt + qt^(2) + r… Displacement (y) of a body is represented by y = pt + qt^(2) – rt^(3)… Displacement (y) of a body is represented by y = pt + qt^(2) – rt^(3)… A body of mass 2 kg is moving according to the equation for displaceme…

What is the formula for velocity of a collision?

What is the formula of collision? From the conservation of momentum, the formula during a collision is given by: m1v1 + m2v2 = m1v’1 + m2v’2. If the collision is perfectly inelastic, the final velocity of the system is determined using v’ = (m1v1 + m2v2)/m1 + m2.

What is the formula for the velocity of a particle after a collision?

If two particles are involved in an elastic collision, the velocity of the second particle after collision can be expressed as: v2f=2⋅m1(m2+m1)v1i+(m2−m1)(m2+m1)v2i.

What happens when two objects of equal mass and velocity collide?

When two objects with the same mass collide, Newton’s laws tell us that they will accelerate the same amount but in opposite directions. Recall that force, velocity, and acceleration have both magnitude and direction. We use positive and negative signs to indicate the direction of each of these quantities.
