Answer:
9.8 x 2.2 = 21.56 m
distance = time x speed
speed = distance ÷ time
Step-by-step explanation:
The highest point he reached occurred at the vertex, which is at t = -b/2a = 2.2 second. Plugging in t = 2.2
9.8 x 2.2 = 21.56ft
Higher cliffs don't accelerate your fall -- acceleration is constant during free fall. The pull of gravity decreases infinitesimally at higher elevations, but it pulls you with an equal force from the first second of your jump until you decelerate when you hit the water.
Answer: Your answer here is D: y = 5x - 1

Answer:
12.96
Step-by-step explanation:
since it is a square, both sides are equal. to find the area of any square, it is the side squares. since you are given what the area is, simply square root 168.
which is about 12.96
The scale is likely to show the mass is either 270.9g or 245.1g
Step-by-step explanation:
Actual mass = 258g
Percent error = 5% = ±0.05
Mass shown by scale = Actual mass*percent error
Therefore,
Mass shown by scale = 258+12.9 , Mass shown by scale = 258-12.9
Mass shown by scale = 270.9g , Mass shown by scale = 245.1g
The scale is likely to show the mass is either 270.9g or 245.1g
