A small ball of mass m1=0.84kg and initial speed v1=18.2m/s makes a collision with another ball of mass m2 =1.4kg which is initially at rest on a frictionless horizontal table. After the collision the balls move as shown in the figure. Given θ=240, determine the speed of m2 just after the collision, that is, v2'=? Express your answer using one decimal place.

You have been called to testify as an expert witness in a trial involving a head-on collision. car a weighs 1515 lb and was traveling eastward. car b weighs 1125 lb and was traveling westward at 44.0 mph. the cars locked bumpers and slid eastward with their wheels locked for 22.5 ft before stopping. you have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750 . how fast (in miles per hour) was car a traveling just before the collision? (this problem uses english units because they would be used in a u.s. legal proceeding.)

The earth is constantly spinning on its axis, like you might spin a basketball on your finger. it is this spinning of the earth that causes
