Chapter 17, Problem 34

(choose chapter or problem)

A particle is moving on a path in the xz-plane given byx = 20t, z = 5t 0.5t2, where z is the height of theparticle above the ground in meters, x is the horizontaldistance in meters, and t is time in seconds.(a) What is the equation of the path in terms of x and zonly?(b) When is the particle at ground level?(c) What is the velocity of the particle at time t?(d) What is the speed of the particle at time t?(e) Is the speed ever 0?(f) When is the particle at the highest point?
