Roadrunner is being chased by Wile E. Coyote, suddenly Roadrunner changes direction. Wile E. Coyote can accelerate at -0.5m/s. If Wile E. Coyote was initially moving at 10m/s, what
was his braking distance?
( Need work shown kinematic equation)

Molten iron fills a mould, which has a volume of 200 cm cubed. calculate the volume when the iron cools and solidifies.

The metric unit of electrical power is the watt volt ampere ohm

(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.)
