- A bumper cap "A" (mass of A = 140kg) with a velocity of 15 km/hr hits a another car "B" (mass of B = 160kg) which was immobile before impact. The collision is perfectly elastic & the frictions are considered negligible. Calculate the time at which the bumper cars are 2m apart from each other after the collisionParticles are moving speeds of v₁ = 5.2 m/s. After the collision a+ and V₂=0 and m₂ = 2m₁. is observed to be moving mass mi f 90° relative to its direction Prior to e collision is elastic. an angle the Collis Eine a Suitable coordinate system and determ may final velocities (including direction) of each Partille, be useful to remember that cos(20)= Cos²-si- 9150In a system with two moving objects, when a collision occurs between the objects: the total kinetic energy is always conserved. the total momentum is always conserved. neither the kinetic energy nor the momentum is conserved. the total kinetic energy and total momentum are always conserved.
- A 3 kg object is moving at 4 m/s. It collides inelastic collision with a 6 kg object moving to the left at 5.0 m/s. find their combined speed after the collision. (include their direction left or right)A 0.500 kg block of cheese sliding on a frictionless tabletop collides with and sticks to a 0.200 kg apple. Before the collision the cheese was moving at 1.40 m/s and the apple was at rest. The cheese and apple then slide together off the edge of the table and fall to the floor 0.600 m below. (a) Find the speed of the cheese and apple just after the collision. In this collision, what is conserved: momentum, total mechanical energy, both, or neither? (b) What is the speed of the cheese and apple just before they hit the floor? During the fall from the tabletop to the floor, what is conserved: momentum, total mechanical energy, both, or neither?In this problem we will consider the collision of two cars initially moving at right angles. We assume that after the collision the cars stick together and travel off as a single unit. The collision is therefore completely inelastic Two cars of masses my and me collide at an intersection. Before the collision, car 1 was traveling eastward at a speed of v1, and car 2 was traveling northward at a speed of v. (Figure 1)After the collision, the two cars stick together and travel off in the direction shown.
