What is the velocity of a particle moving? The velocity (v) of a particle of mass m moving along x-axis is given by v=α√x, where α is a constant. What is the acceleration of a particle moving along a straight line...
What is a 200g firework? 200 gram multi-shot fireworks repeaters are also known as 200 gram cakes. These fireworks function like the larger 500 gram fireworks cakes. They have several tubes fused together so you light one fuse, step back and...
What is the momentum of the two cars after collision if its momentum before collision is 50 kgm s? Let, P = Momentum of car 2 after the collision. Total initial momentum = Initial momentum of car 1 + Initial momentum...
How do you calculate elastic collision? Step 1: Identify the mass and velocity of each object and the direction they are traveling before the collision. Step 2: Plug the mass and velocity of each object into the equation for conservation of...
How do you calculate the velocity of the two vehicles after the 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...
How much work is done in accelerating a 2000 kg car from rest to a speed of 30m s? 900,000 J. The work done to accelerate a 2000 kg. car from rest to 30 m/s is equal to the change in...
What is the momentum of a 20 kg body moving with a velocity of 10 m per second? Hence the momentum of the body is 200 kg. m/s. What is the speed of a 1.0 x10 3 kilogram car? A 1.0...
What force prevents the monkey from falling to the ground? Both gravitational and frictional forces act on monkey. If both forces are equal (or) if the friction is greater than gravity the monkey remains on the vine. What are the forces...
What happens in an elastic collision between two objects of unequal masses? 15.4 Elastic Collision of Two Unequal Mass Objects A smaller mass approaching a larger mass will bounce back in a collision. If a larger mass is intially moving toward...
What is a body of mass 20 kg moving with velocity 5m s? Detailed Solution The correct answer is 250 J. Given, mass (m) = 20 kg, velocity (v) = 5 ms-1. So, the kinetic energy of the object is (½)∗20∗52...
