Physics 1: Impulse and Momentum
A 2kg car is traveling east at 3 m/s and a 4kg car is traveling west at 6 m/s. Assume the cars collide and stick together. Find the direction and velocity of the cars after they collide.
A champagne bottle of mass 90 g has a 2 g cork in it. The pressure built up in the bottle causes the cork to shoot out, as shown below. If after the explosion, the bottle is moving directly to the left at 4 m/s, what is the velocity of the cork?
A crash test car of mass 1,000 kg moving at a constant speed of 12 m/s collides completely inelastically with an object of mass M at time t = 0. The ojbect was initally at rest. The speed v in m/s of the car object system after the collision is given as a function of time t in seconds by the expression
A. Calculate the mass M of the object
B. Assuming an initial position of x = 0, determine an expression for the position of the car object system after the collision as a function of time t.
C. Determine an expression for the resisting force on the car object system after the collision as a function of time t.
D. Determine the impulse delivered to the car object system from t = 0 to t = 2.0 s.
