Explanation:
Distance = Total path length = 35m + 35m = 70m
Displacement = Final - Initial position = 0m
Answer:
v = 6.95 m/s
Explanation:
Given that,
A diver is on a board 1.80 m above the water, s = 1.8 m
The initial speed of the diver, u = 3.62 m/s
Let v is the speed with which she hit the water. It will move under the action of gravity. Using the equation of motion as follows :

So, she will hit the water with a speed of 6.95 m/s.
Answer:
m/s
Explanation:
Assumptions: 0° is true North, and 90° is east (along the x-axis).
To solve this problem we must use the expression:

Where
is the velocity in the y-direction (East),
is the total velocity in the direction which the aircraft is travelling, and
is the direction the aircraft is travelling (angle from the y-axis).
Using the equation above, we obtain the y-component of velocity
m/s which is rounded to 227 m/s (due to the number of significant figures in the question).
