<h2><u>Answer:</u></h2>
As you are looking for a new tennis partner. People should keep in mind that they should go for the one who most likely demonstrate good sportsmanship
Luis, when you pursue the principles in tennis, you realize when to talk up, you don't blast a racquet or shout, holler.
Whatever it is following the principles and being respectful it the most ideal approach.
To analyze the differences in acceleration of the two objects, a necessary formula/relation to remember here is force = mass * acceleration. Given the different data in the problem, we can solve for the acceleration of each object. This is shown below:
Force = 15 N
M1 = 25 kg
M2 = 50 kg
a1 = ?
a2 = ?
For object 1:
15 N = 25 kg * a
a = 0.6
For object 2:
15 N = 50 * a
a = 0.3
Therefore, the acceleration of Object B is half that of Object A.
Answer:
224236.76 W
Explanation:
Power: This can be defined as the rate of change of energy. The S.I unit of power is Watt(W).
From the question,
P = E/t ......................... Equation 1
Where P = power, E = Energy or work, t = time.
But,
E = Wt×d.................. Equation 2
Where Wt = Total weight of the passengers, d = distance.
Substitute equation 2 into equation 1
P = (Wt×d)/t.............. Equation 3
Given: Wt = 590×150 =88500 N, d = 244 m, t = 96.3 s.
Substitute into equation 3
P = (88500×244)/96.3
P = 224236.76 W
Vertical acceleration = 300 m/s²
Initial vertical velocity = 0
Time of flight = 8.0 s
Calculate the height after 8 s.
h = (1/2)*(300 m/s²)*(8.0 s)² = 9600 m
Answer: 9600 m
