Uniformly Accelerated Motion.

Correct answer please

apply! Assessment 1. One of the presentation shown during the 2019 intramurals is the log rolling. From rest, the participants accelerate uniformly at 5.25 s and covered a distance of 4.125 m before turning. Determine their acceleration. Given: Unknown: Solutions: 2. Jenny, a grade 12 student is playing sipa one recess time with her friends when she hits the . improvised paper ball hard upward and reach a height of 10m. What is the final velocity before reaching its maximum height? Unknown: Given: Solutions:3. A grade 12 student threw ball vertically upward with an initial velocity of 2 m/s and was able to catch it before it reach the ground on its return. Given: Unknown: A. What was its velocity after 1 second? Solutions: B. What was its displacement in the first second? Solutions: C. How long did it take the ball to reach its maximum height? (Note: An object thrown upward will reach a maximum height where it will momentarily stop and then start to move down. At this point Vf (upward)=0, VF (downward) = 0.) Solutions: D. How far was the maximum height from the starting point? Solutions:E. What was its final velocity just before it touched student's hand? Solutions: Enrichment 1. A ripe guava freely dropped and reach the ground after 2s. What is the final velocity of the ripe guava? Given: Unknown: Solutions: 2. An airplane from rest accelerates on a runway at 4.50 m/s for 15.25 seconds until it finally takes off the ground. What is the distance covered before take off? Given: Unknown: Solutions
