The formula for force applied on an object is F=ma, where F equals force applied, m equals mass and a equals acceleration. Since the car and the truck are moving at with the same momentum, their …

4.3ms^-1 and 75.9J Conservation of momentum states that before and after a physical reaction there must always be the same amount of momentum. Momentum is the product of mass and velocity, or …

The angular momentum, #I#, for a solid disk is given by #I = (M*r^2)/2# #I = (6 kg* (5 m)^2)/2 = 75 kg*m^2# Going back to the formula for torque, #tau = 75 kg*m^2*8.4 (radians)/s^2 = 630 N*m# …

1.IA : IB = 1: 2 2. pA : pB = 1:1 3.FA : FB = 1:1 Given that Two balls are in motion: A has mass m and velocity 2v and B has mass 2m and velocity v To do : Compare :- 1. Their inertia 2. Their momentum …

The momentum of the first object #,p_1=m_1v_1=10v_1# #:. # the momentum of the second object #,p_2=m_2v_2=15v_2# As,you mentioned #p_1=p_2# Hence, #m_1v_1=m_2v_2# #or,10v_1=15v_2#

But this is true only if #P="constant"# i.e., the total momentum is conserved or the initial momentum MUST be equal to the final one!

Another way of looking at velocity is to consider a moving object's momentum. Momentum is the object's mass multiplied by its velocity p = mv. Momentum is conserved in the absence of an external force.

Let v be the velocity of the wooden block with bullet embedded in it. Using Law of conservation of momentum we have "Initial momentum "=" Final momentum" Inserting given values we get yxx …

We know that magnetic field can change the direction of the motion of a charged particles, but it will not change its speed*. Similarly, direction of momentum changes but magnitude of momentum does not …

The post-collision velocity of the 22 kg ball is 9 ms^-1. The difference in kinetic energy before and after the collision is 1782-891=891 J, and this is the energy lost as heat (and probably sound). Momentum …
