3. A bunny and a tortoise start a race from rest. The bunny accelerates at a rate ab for a time to until it reaches its maximum speed (vb) after traveling a distance db. The tortoise accelerates at a rate one forth as great as the bunny and
takes three times as long to reach its maximum speed of vt after traveling a distance dt.

a) What is the maximum speed of the tortoise? Answer in terms of vb

b)How far did the tortoise travel? Answer in terms of db

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
