Activity 1: Problem SolvingDirections: Show your complete solutions for the following worded problems.1. A flower pot falls a window of a three-storey apartment. How far has it fallen after 2seconds? What is the pot's velocity after I s of fall? after 2 seconds of fall?2. A brick falls freely from a high scaffold and hits the ground after 3.5 seconds. Howhigh is the scaffold? What is the velocity of the brick just before hitting the ground?3. Alice thrown a ball upwards vertically from the roof of a building. The ball leaves herhand at a point level with the roof railing with an upward speed of 15 m/s. On its wayback down, it just misses the railing. Find (a) the ball's position and velocity 1.0 s and4.0 s after leaving her hand; (b) the ball's velocity when it is 5.0 m above the railing;(c) the maximum height reached. olem 1.A stone is dropped from the top of a building and falls freely from rest.
