A crash test car of mass 1,000 kg moving at constant speed of 12 m/s collides completely inelastically with an object of mass M at time t = 0. The object was initially 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 v=s/1+5la. 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 tot = 2.0 s.
