Caelyn wanted to find out what shampoo made her hair the shiniest . Everyday she washed her hair with different shampoos and then rated how shiny her hair was, on a scale from 1-10. She used Pantene, Herbal Essences, L’Oreal, and just water

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]

Crowbar of 5 metre is used to lift an object of 800 metre if the effort arm is 200cm calculate the force applied

(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.)
