Answer:
Explanation:
b) Gravity reduces the initial upward velocity to zero in a time of
t = v/g = 40/10 = 4 s
a) h = v₀t + ½gt² = 40(4) + ½(-10)4² = 80 m
or
v² = u² + 2as
h = (0² - 40²) / 2(-10) = 80 m
Perpendicular slope would be 1/3. so the equation will be Y=1/3x -4
Answer:
it can be calculated by measuring the final distance away from a point, and then subtracting the initial distance
