Answer:
2621.25 meters
Explanation:
First, write down what we are given.
Initial velocity = 27.5 m/s
Final velocity = 42.4 m/s
Time = 75 seconds
We need to look at the kinematic equations and determine which one will be best. In this case, we need an equation with distance. I am going to use 
, but you can also use the other equation, 
We need to find acceleration. To find it, we need to use the formula for acceleration: 
. Plugging in values, 
Next, plug in what we know into the kinematics equation and solve for distance. 
Answer:
By using Pythagoras Formula
Explanation:
Measure the distance man is sliding. “It will be c”
Measure the distance of between the tower and a post with which wire is attached. It will be “b”
Then apply Pythagoras Formula c2=a2 + b2 and solve it.
It will give the height of tower.
Answer:
The correct answer is "1080 W".
Explanation:
Given:
Current,
I = 9.0 A
Potential difference,
V = 120 volt
As we know,
⇒ 
On substituting the values, we get
⇒ 
⇒ 
Answer:
F = N*μ or F =m*g*μ
Explanation:
The friction force is defined as the product of the normal force by the corresponding friction factor.
When a body is in equilibrium over a horizontal plane its normal force value shall be equal to:
![N = m*g\\where:\\m=mass [kg]\\g=gravity [m/s^2]\\N= normal force [N]](https://tex.z-dn.net/?f=N%20%3D%20m%2Ag%5C%5Cwhere%3A%5C%5Cm%3Dmass%20%5Bkg%5D%5C%5Cg%3Dgravity%20%5Bm%2Fs%5E2%5D%5C%5CN%3D%20normal%20force%20%5BN%5D)
if we simplify this formula more for a balanced body on a horizontal plane, we will have.
