Answer:
135.7 milliseconds
Step-by-step explanation:
The relationship between force, mass, and acceleration is ...
F = Ma . . . . . we use M for mass, so as not to confuse with m for meters
The relationship between acceleration, velocity, and time is ...
v = at
The fraction of the applied force that is in the horizontal direction is ...
2000N·cos(20°)
Solving for a and t, we get ...
a = F/M
t = v/a = v/(F/M) = Mv/F
t = (85 kg)(3 m/s)/(2000cos(20°) kg·m/s²) ≈ 0.1357 s
The sprinter took about 135.7 ms to push off.
Answer:
1) The first option
2) -9, -7, 6, 8, 10
3) Rise by 10 degrees
Step-by-step explanation:
Ascending is from smallest to biggest therefore you start with the smallest negative number and end with biggest whole number.
Answer:
Warrior WiFi is better because it costs 167.50 for 175 texts.
Step-by-step explanation:
2x175 = 350 + 20 = 370
0.50x175 = 87.5 + 80 = 167.5
Answer:
The correct option to tell whether a relationship is proportional or not is;
![\dfrac{y}{x}](https://tex.z-dn.net/?f=%5Cdfrac%7By%7D%7Bx%7D)
Step-by-step explanation:
A proportional relationship is a relationship between two variables, 'x', and 'y' such that they have equivalent ratio, such that all values of variable 'y' are given by the product of the values of the variable 'x' and a constant, 'k'
Therefore, y = k · x, from which we have;
![\dfrac{y}{x} = k = Contant](https://tex.z-dn.net/?f=%5Cdfrac%7By%7D%7Bx%7D%20%3D%20k%20%3D%20Contant)
Therefore we can use
to tell whether a relationship is proportional or not proportional.
