A 6.00kg ball with a velocity of 9.00m/s along the positive x-axis collides with another ball of mass 0.800kg that is initially at rest. The collision last 0.250s. After collision, the 0.800kg ball has a velocity of 15.0m/s at 65.0°.

The most important difference between a wedge and an inclined plane is a. their size b. their shape c. how they are used d. what they are made of

Asystematic approach to problem solving is called a (an)

(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.)
