A 1,295-kg car traveling initially with a speed of 25.0 m/s in an easterly direction crashes into the rear end of a 9,600-kgtruck moving in the same direction at 20.0 m/s (see figure below). The velocity of the car right after the collision is 18.0 m/s to the east. Two images depicting a before and after scenario of a car colliding with the back of a truck. Before: The car is moving at a velocity of +25.0 m/s. This is shown as a rightward-moving horizontal arrow above the car. The truck is moving at a velocity of +20.0 m/s. This is shown as a rightward-moving horizontal arrow, shorter than that of the car, above the truck. After: The car is shown crashing into the back of the truck. At this point, the velocity of the car is shown to be +18.0 m/s. This is shown as a rightward-moving horizontal arrow above the car. The velocity of the truck is shown to be v. This is shown as a rightward-moving horizontal arrow, longer than that of the car, above the truck. (a) What is the velocity of the truck right after the collision? (Round your answer to at least three decimal places.) 20.94427083 m/s (east) (b) How much mechanical energy is lost in the collision

Batman (mass = 86.5 kg) jumps straight down from a bridge into a boat (mass = 493 kg) in which a criminal is fleeing. The velocity of the boat is initially +13.3 m/s. What is the velocity of the boat after Batman lands in it? Number i Units

As shown in the figure below, two blocks (m1 and m2) are each released from rest at a height of h = 3.53 m on a frictionless track and when they meet on the horizontal section of the track they undergo an elastic collision. If m1 = 2.50 kg and m2 = 4.15 kg,determine the maximum heights (in m) to which they rise after the collision. Use the coordinate system shown in the figure.

A 5000.0-kg truck moving rightward with a speed of 5.00 km/hr collides head-on with a 1000.0-kg car moving leftward with a speed of 20.0 km/hr. The two vehicles stick together and move with the same velocity after the collision. Determine the post- collision velocity of the car and truck. Final velocity = km/hr %3D

A baseball player throws a 0.2 kg ball (Ball A) from the top of a 10 m tall hill with a velocity of 40 m/s. Suppose that another ball (Ball B) with identical mass was dropped, not thrown, from the same height at the same time the first ball was thrown. Which ball hits the ground first? Explain  Suppose another baseball player throws a 0.5-kg ball (Ball C), also at 40 m/s, at the same time, which ball will hit the ground first? Explain.

A 1130 kg car is moving with speed of 19 mph, coming from the south. A 1380 kg car is moving with an unknown speed, coming from the west.The two cars collide and their bumpers interlock.The instant after the collision the cars are moving together with a speed of 28 mph.  What was the speed of the 1380 kg car before the collision? (include units with answer)      Needs Complete handwritten solution with 100 % accuracy don't use chat gpt or ai plz plz plz plz plz.

A 10.0-kg block of ice is sliding due east at 9.00 m/s when it collides elastically with a 6.00-kg block of ice that is sliding in the same direction at 5.00 m/s. Define the positive direction as pointing due east, the 10.0-kg block as block A, and the 6.00-kg block as block B. Determine the velocity vaf of block A after the collision. VAf = m/s due east Determine the velocity UBf of block B after the collision. m/s due east

16 1/1 A 10-kg toy car (m1) approaches an intersection traveling east at v1i. Another 10-kg (m2) toy car approaches the same intersection traveling north at 5.0 m/s (v2i = 0, 5 m/s ). The two cars collide at the intersection and lock together. If the velocity of the locked cars immediatley after the collision is vf = 1.0 m/s, 2.5 m/s , find v1i. Ignore any external forces that act on the cars during the collision. > A: 2.0 m/s, 0 m/s XB: 5.0 m/s, 0 m/s XC: 2.5 m/s, 0 m/s X D: 1.0 m/s, 0 m/s XE: 2.0 m/s, 10 m/s
