Directions: 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 2 seconds? 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. How high 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 her hand at a point level with the roof railing with an upward speed of 15 m/s. On its way back down, it just misses the railing. Find (a) the ball's position and velocity 1.0 s and 4.0 s after leaving her hand; (b) the ball's velocity when it is 5.0 m above the railing; (c) the maximum height reached.

Activity 1: Problem Solving
Directions: 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 2
seconds? 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. How
high 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 her
hand at a point level with the roof railing with an upward speed of 15 m/s. On its way
back down, it just misses the railing. Find (a) the ball's position and velocity 1.0 s and
4.0 s after leaving her hand; (b) the ball's velocity when it is 5.0 m above the railing;
(c) the maximum height reached.
