Disregarding air friction, the distance traveled by an object due to gravity is : H = 0.5*g*t^2. g is the gravitational constant at the surface of earth.
g= 9.81 m/s^2
After 3 seconds, Distance = .5*9.81*9 = 44.15 meters traveled.
Since it was dropped from a height of 90 meters, the current height is 90 - 44.15 = (a) 45.85 meters
(b) It has to travel 90 meters to hit the ground . So we must find t
Using the same equation
t = (2*H/g)^.5
t = (2*90/g)^.5 = 4.28 seconds until it hits the ground
Answer:
you are correct
Step-by-step explanation:
since there is a box in the angle, it means it's 90°, so if the 1rst angle is 30°, the other one has to be 60°
Answer:
There are 4 integers between 27 and 53 that have a remainder of 4 divided by 6.
Step-by-step explanation:
At first we need to find which integers between 27 and 53 are divisible by 6, which are, respectively:
All integers that have a remainder of 4 divided by 6 are found by summing 4 to each element of A, that is:
There are 4 integers between 27 and 53 that have a remainder of 4 divided by 6.
Answer:
$20.16
Step-by-step explanation:
all the costs from the trips added up is $429.84, so subtract that from $450.00 and that's the answer
