A4.86 g bullet traveling horizontally with a speed of 306 m/s is fired into a wooden block with mass 1.37 kg, initially at rest on a level frictionless surface. the bullet takes 0.221 ms to pass through the block and emerges with its speed reduced to 147 m/s. a. how fast is the block moving just after the bullet emerges from it?

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
