- JD is playing with some clay (mass = 18-g). He flings it across the room, where it lodges on the hood of a 259-g toy car that can freely roll back. Once in motion, the clay/car combination moves with a speed of 0.78 m/s. Determine the speed (in m/s) at which the clay was flung.A 1500kg sport car is moving westbound at 20m/s on a level road when it collided with a 4000kg truck driving east on the same road at 15m/s. The two vehicles remain locked together after the collision. a)what are is the magnitude of the velocity of the two vehicles just after the collision?The Hulk (200kg of pure angry muscle)collides head-on with a truck (2500kg). If the Hulk was running at 10.0m/s and the truck was moving at 15.0 m/s in the opposite direction, after they stick together, what is their speed (in m/s)? Either the Hulk or the truck needs a negative initial velocity.
- Two objects with different masses have the same momentum. The less massive object will have a greater kinetic energy. True or FalseA 18.3kg object, initially at rest, explodes into 3 pieces! After the explosion, Piece A (3.3kg) is moving 6m/s at an angle 64° North of East. Piece B (7.6kg) is moving 3.4m/s at an angle 76° South of West. The third piece, Piece C, is not shown after the explosion.

Iply unit before after B A W+ N ·50 S Ethis is a multi step problem but I am just having trouble with this part of the problem. Here are the values that I correctly calculated: mass of particle 1=6 kg initial velocity for particle 1= 185i+138j final velocity for particle 1= -68.89i+-50.67j F21=-15.9e-t/96i+-100sin(2πt/96)j I am trying to find: What is the x displacement for particle 1? I think that I need to use Newtons second law to get an expression for acceleration, and then integrate but I am not getting the right answers.
