A1500 kg car travels at 90 km/h east and collides with a 1000 kg car traveling at 60 km/h north. the two cars stick together after the collision. the road surface conditions were wet such that us= 0.5 and uk = 0.4. what is the speed of the cars, in m/s, immediately after the collision? what is the direction of the velocity of the cars immediately after collision? how far did the two vehicles skid, in meters, after the collision?

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
