- First 2 parts quickly plz!!!hw49 Somebody please help me figure out the last part of this question, thank you274 After slapping the burglar in the Tondo, Rodrigo ran to a nearby hut which is s = (300+) meters from 100 where he slapped the burglar. He then ran towards the hut covering a distance defined by the function s = 1.25t-0.35 – 3t3 cos(-5t) + 0.25t4e0.5t, where s is expressed in meters, t is time in seconds, and the angles are in radians. Unfortunately, 500 milliseconds after he started to ran, Berto, came in where Rodrigo slapped the burglar, saw him escaping and chased after him with a velocity defined by the v-t curve below. 1. Was Berto able to capture Rodrigo? Explain. 2. Determine the velocity and acceleration of Berto and Rodrigo 3 seconds after Rodrigo started to ran. 3.
