Answer:
Explanation:
v = Velocity of Ferdinand = 5 m/s
= Angle of jump
T = Time taken = 0.6 s
R = Distance between lily pads = 2.4 m
Horizontal range is given by
The angle at which Ferdinand make each of his jumps is
I can think of two possible and logical questions for the problem given. First, you can calculate for the maximum height reached by the blue ball. Second, you can compute the length of time for the two balls to be at the same height. If so, the solution are as follows:
When the object is thrown upwards or when the object is dropped from a height, the only force acting upon it is the gravitational force. Because of this, it simplifies equations of motion.
1. For the maximum height, the equation is
H = v₀²/2g
where
v₀ is the initial speed
g is the acceleration due to gravity equal to 9.81 m/s²
For the blue ball, v₀ = 21.8 m/s. Substituting the values:
H = (21.8 m/s)²/2(9.81m/s²)
H = 24.22 m
The maximum height reached by the blue ball is 24.22 m + 0.9 = 25.12 m.
2. For this, you equate the y values of both balls:
y for red ball = y for blue ball
v₀t + 0.5gt² = v₀t + 0.5gt²
(10.4 m/s)t + 0.5(9.81 m/s²)(t²) + 26.6 m = (21.8 m/s)t + 0.5(9.81 m/s²)(t²) + 0.9 m
Solving for t,
t = 2.25 seconds
Thus, the two balls would be at the same height after 2.25 seconds.
Answer:
works out for only one week
Explanation:
In order to develop a good habit, there are certain things that you can do like:
-Develop a consistent schedule of exercise which allows you to work everyday over a period of time which helps you to create a routine that you would get used to it creating a habit.
-Work out with a friend which allows you to have someone to motivate you and that would go everyday with you which would help to be consistent.
-Use success strategies that are ways in which you can achieve your goal of creating a good habit to exercise.
According to this, the option that would not help Bob develop a good habit is if he works out for only one week as doing something everyday is what would help you to create the habit.
Answer:
Explanation:
Required
The units of A and B
From the question, we understand that:
This implies that each of 
and 
will have the same unit as 
So, we have:
The unit of t is (s); So, the expression becomes
Divide both sides by
