Suppose a scientist were to drop a cannonball from the leaning tower of pisa from a height of 180 ft. which expression could be
2 answers:
The vertical height is h = 180 ft
The acceleration due to gravity is g = 32.2 ft/s²
Let t = the time for the cannonball to hit the ground.
Because the initial vertical velocity is zero (the ball is dropped), the formula to use is
h = (1/2)gt²
That is
t = √[(2h)/g]
= √[(2*180)/32.2]
= 3.344 s
Answer:
The formula is

Answer:
he maximum frequency occurs when the denominator is minimum
f’= f₀
Explanation:
This is a doppler effect exercise, where the sound source is moving
f = fo when the source moves towards the observer
f ’=f_o Alexandrian source of the observer
the maximum frequency occurs when the denominator is minimum, for both it is the point of maximum approach of the two objects
f’= f₀
