The ball rolled for 13.2 s
<h3>Further explanation</h3>
Speed is scalar and no direction

A bowling ball rolls 33 m, with average speed = 2.5 m/s
So elapsed time :

" <em>Energy is never created or destroyed.</em> "
All the rest is commentary.
Answer:
Mass of the sled in the snow 83.33 kg.
<u>Explanation</u>:
Given that,
Force applied to move the sled in the snow (F) = 75N

We know that
Newton's second law of motion is

F = ma (Or "force" is equal to "mass" times "acceleration".)
So if we move this around we can isolate mass and get mass


M = 83.33 kg
Mass of the sled in the snow <u>83.33 kg.</u>
Answer:
Δ h = 52.78 m
Explanation:
given,
Atmospheric pressure at the top of building = 97.6 kPa
Atmospheric pressure at the bottom of building = 98.2 kPa
Density of air = 1.16 kg/m³
acceleration due to gravity, g = 9.8 m/s²
height of the building = ?
We know,
Δ P = ρ g Δ h
(98.2-97.6) x 10³ = 1.16 x 9.8 x Δ h
11.368 Δ h = 600
Δ h = 52.78 m
Hence, the height of the building is equal to 52.78 m.
Answer:
x-component=-9.3 m
Magnitude of A=17.7m
Explanation:
We are given that


We have to find the x-component of A and magnitude of A.
According to question

Substitute the values then we get


m




The value of x-component of A is negative because the vector A lie in second quadrant.
Hence, the x- component of A=-9.3 m
