Acyclist accelerates from 0 m/s to 8 m/s in 3
seconds. what is his acceleration?

Akg a of 55 m at an of 11 ? . if is at 98 km/h,be ?

(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.)

What sort of waves exhibit the doppler effect?
