A car with a mass of 1040 kg and a speed of v1 = 15.0 m/s
approaches an intersection, as shown in the figure. A 1270 kg
minivan traveling at v2 is heading for the same intersection. The
car and minivan collide and stick together. The direction of the
wreckage after the collision is theta=40.0 degrees above the x
axis.
Part A) Find the initial speed of the minivan, assuming external
forces can be ignored (in m/s).
Part B) Find...

3. A car with a mass of 950 kg and a speed of 16 m / s approximates an interception. A 1300 kg minivan traveling at 21 m / s is approaching the same interception. The car and the minivan collide and stay together. Find the speed and direction of the vehicles just after the collision, assuming that external forces are ignored.

Physics 2018-2019 Lesson Check 7.57 Constants A 950-kg red car (Figure 1) with a speed of v 20.0 m/s approaches an intersection, traveling in the positive u direction. A 1300-kg blue minivan is heading for the same intersection in the positive y direction. The car and minivan collide and stick together, producing wreckage that moves at an angle of θ= 40.0, relative to the positive rats. PartA Find the initial speed of the blue minivan.

A car with a mass of 980 kg is initially traveling east toward
an intersection with a speed of vc = 20.9 m/s and a 1500 kg pickup
is traveling north toward the same intersection. The car and truck
collide at the intersection and stick together. After the
collision, the wreckage (car and truck) moves off in a direction of
44.0° above the x-axis. Determine the initial speed of the truck
and the final speed of the wreckage in meters...

A 1000-kg car approaches an intersection traveling north at 15.0 m/s. A 1300-kg car approaches the same intersection traveling in the same direction behind first car at at 28.0 m/s. The two cars collide at the intersection and lock together. Ignoring any external forces that act on the cars during the collision, what is the velocity of the cars immediately after the collision?
