A square energy pulse traveling to the right with a speed v-2 m/s is given by the equation: f(x, t)-E if Ix-vtl a. Plot this pulse as a function of x at t-0.
b. Plot this pulse as a function of x at t-4 s.
c. Expand this pulse as an infinite superposition of harmonic traveling waves of the type cos(ot-kx) where co/k-v

Two students, each riding bicycles, start from the same apartment building and ride to the same building on campus, but each takes a different route. the first student rides 1100 m due east and then turns due north and travels another 1430 m before arriving at the destination. the second student heads due north for 1930 m and then turns and heads directly toward the destination. at the turning point, how far is the second student from the destination?
