Rate of change of velocity is acceleration
They stay with the microscope as it moves around to different schools, and they are always located in the same classroom where the rest of the microscope is being used.
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
