1. A boy on a 20-m high platform throws a ball at a distance of 5 m. At what speed is the ball thrown? (See the diagram) Solution: Given: dx Find : Vox (Vox = 4) Since d = 5 m, then we need to find the time t, yet from d = X y 5 m; horizontal distance dy = 20 m; vertical distance t = √ Hence, Vox = dx t /2(20) 9.8 5m sec. m/s gta, or or t = √ 2dy g 20m 5 m

274 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.

1. Kenny is climbing the stairs of his apartment building for exercise. Kenny weighs 83 kg. There are 8 steps in each flight and the height of a single step on the staircase is 11 inches. He climbs the flight of stairs in 3.4 seconds. a.) calculate the long-term rate at which stairs can be climbed considering the given information.(how long can be sustained in stair per second) b.) Why does Kenny descend stairs at a faster rate for a nearly unlimited time although very similar forces are exerted descending as they are ascending?(This points to a fundamentally different process for descending versus climbing stairs.)
