The two cars collide at right angles in the intersection of two icy roads. Car A has a mass of 1040 kg and car B has a mass of 1005 kg. The cars become entangled and move off together with a common velocity in the direction indicated. If car A was traveling 44 km/h at the instant of impact, compute the corresponding velocity of car B just before impact. 25 A= 44 km/h Answer: VB km/h

Current Attempt in Progress A car is traveling around a circular track of 670-ft radius. If the magnitude of its total acceleration is 6.1 ft/sec² at the instant when its speed is 33 mi/hr, determine the rate at at which the car is changing its speed. Answer: at = ±i eTextbook and Media ft/sec²

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 5.70 m/s, and bumper car 2 is traveling 78.2° south of west at 4.20 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. W-O>E Car 2 Car 1 Vii (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 driver on a level two-lane highway observes a truck completely blocking the highway. The driver was able to stop her vehicle only 10 ft from the truck. If the driver was driving at 70 mi/h, how far was she from the truck when she first observed it (assume perception-reaction time is 2.0 seconds)? How far was she from the truck at the moment the brakes were applied (use a/g=0.35)?
