Two bumper cars at the county fair are sliding toward one another (see figure below). Initially, bumper car 1 is traveling to the east at 5.65 m/s, and bumper car 2 is traveling 77.7° south of west at 4.10 m/s. They collide and stick together, as the driver of one car reaches out and grabs hold of the other driver. The two bumper cars move off together after the collision, and friction is negligible between the cars and the ground. Car 2 W-OE Car 1 (a) If the masses of bumper cars 1 and 2 are 596 kg and 625 kg respectively, what is the velocity of the bumper cars immediately after the collision? magnitude m/s direction ° east of south (b) What is the kinetic energy lost in the collision?
A 72.5 kg projectile is used to deflect a 200 kg boulder heading towards a small town. The projectile is travelling 13.4 m/s in a southwest direction (an angle of 280 north of west). While the boulder is travelling at 8.18 m/s due north. After the impact the projectile comes to a complete rest. What is the velocity of the of the boulder?
In Figure (1), a 3.50 g bullet is fired horizontally at two blocks at rest on a frictionless table. The bullet passes through block 1 (mass 1.36 kg) and embeds itself in block 2 (mass 2.03 kg). The blocks end up with speeds v₁ = 0.680 m/s and v₂ = 1.50 m/s (see Figure (2)). Neglecting the material removed from block 1 by the bullet, find the speed of the bullet as it (a) leaves and (b) enters block 1. 1 (1) (2) Frictionless
You wake up one morning to find yourself in a strange room with opaque walls, and no visible doors or windows. You decide to do some experiments to find out more about your strange situation. Your own body mass is 59.1 kg. This time you drop a ball from a height of 1.93 m and it hits the floor 0.251 s after you drop it. This time you suspect you are on a rocket that has just left the surface of the Earth, and is still not too far above the ground. What do you deduce the rocket s acceleration to be? 82.4 m/s^2 51.5 m/s^2 71.1 m/s^2 61.3 m/s^2
In a ballistic pendulum experiment, a small marble is fired into a cup attached to the end of a pendulum. If the mass of the marble is 0.0295 kg and the mass of the pendulum is 0.250 kg, how high h will the pendulum swing if the marble has an initial speed of 5.75 m/s? Assume that the mass of the pendulum is concentrated at its end so that linear momentum is conserved during this collision. .0174 h = Incorrect
At the intersection of Texas Avenue and University Drive, a yellow, subcompact car with mass 950 kg traveling east on University collides with a maroon pickup truck with mass 1700 kg that is traveling north on Texas and ran a red light (Figure 1).
