Answer:
The vertical distance traveled is 3.18 m.
Explanation:
In order to find the vertical distance traveled by a body in free fall motion, starting from rest to a velocity of 7.9 m/s. For this purpose, we use Newton's third equation of motion,
2as = Vf² - Vi²
where,
a = g = 9.8 m/s²
s = vertical distance = Δy = ?
Vf = final velocity = 7.9 m/s
Vi = initial velocity = 0 m/s
Therefore,
2(9.8 m/s²)Δy = (7.9 m/s)² - (0 m/s)²
Δy = (7.9 m/s)²/(2)(9.8 m/s²)
<u>Δy = 3.18 m</u>
Work = force × distance, assuming that the force is parallel to displacement.
Work L=75×5=375J

Explanation:
hii! for PTM(physics and math tutor) you simply type in the search bar for example in. physics Units and measurements past papers.Then the first option would be PTM(physics and math tutor) and you click on it and it would give you on the left side Revision Notes, flashcards and practice questions. This site has helped me so much and I hope this helps you too (by the way PTM has for all 3 sciences and math too) just simply type the lesson name along with past paper and click on the first link and you'll get yourself your answers!!!! hopefully this helps!:))
