A 40kg trunk sliding across a floor slows down from 5.0 to 2.0m/s in 6.0S. Assuming that the force acting on the trunk is constant, find its magnitude relative to its velocity vector of the trunk.

Which property of fossils allow scientists to determine the relative rock ages..

In the circuit shown below, with each bulb holding a resistance of 60 ohms, how many amps of current are flowing? express your number as a decimal.

(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.)
