If the first vehicle was traveling east with a velocity of 10 m/s and the second vehicle traveling west with a velocity of 9 m/s. Find the final speeds and direction of the two vehicles.

A man in a rowboat on a lake. The man's mass is 67 kg, and the rowboat's is 117 kg. The man and rowboat are initially at rest when the man throws a package of mass m = 15 kg horizontally to the right with a speed of vi = 4.0 m/s. What is the velocity of the rowboat after the package is thrown? Neglect any resistance force from the water. (Give the magnitude in m/s, and select the correct direction from the options given.)   magnitude m/s direction      - toward the right - toward the left - downwards -upwards

Two cars collide at an intersection. Car A, with a mass of 2000 kg , is going from west to east, while car B , of mass 1500 kg , is going from north to south at 13 m/s . As a result of this collision, the two cars become enmeshed and move as one afterward. In your role as an expert witness, you inspect the scene and determine that, after the collision, the enmeshed cars moved at an angle of 55 ∘ south of east from the point of impact. How fast were the enmeshed cars moving just after the collision? 6.8m/s How fast was car A going just before the collision?

A freight train is being assembled in a switching yard, with two boxcars. Car 1 has a mass of m1= 61x10^3 kg and moves at a velocity of Vo1= +1 m/s. Car 2, with a mass of m2= 92x10^3 kg and a velocity 0f Vo2= +1 m/s, overtakes car ! and couples to it. Neglecting friction, find the common velocity (m/s) of the cars after they become coupled. Express in 3 decimal places.

On a horizontal frictionless table, masses A and B (3 kg, 5 kg) slide to the right and left, respectively. They have speeds of 3 m/s and 1 m/s, respectively. The two masses collide, and bounce off each other. After the collision, they travel in opposite directions at speeds of 1.5 m/s and 1.700 m/s, respectively. (Note:In this problem, please use + dir = right, - dir = left, to indicate direction.) a.)

A ball of mass 179 g is thrown with an initial velocity of 25 m/s at an angle of 30° with the horizontal direction. Ignore air resistance. What is the momentum of the ball after 0.8 s? (Do this problem by finding the components of the momentum first and then constructing the magnitude and direction of the momentum vector from the components. Find the magnitude in kg · m/s and the direction in degrees counterclockwise from the +x-axis. Assume the +x-axis points horizontally to the right.) magnitude _____ kg · m/s direction ______ ° counterclockwise from the +x-axis
