Answer: 1433.3 m/min
Explanation:
For 86 Km/h converted to a (m/min), convert kilometers to meters, and hour to minutes
So, 86 Km/h means 86 kilometers per 1 hour
- If 1 kilometer = 1000 metres
86 kilometers = 86 x 1000 = 86,000m
- If 1 hour = 60 minute
1 hour = 60 minutes
In m/min: (86,000m / 60 minute)
= 1433.3 m/min
Thus, 86 Km/h convert to 1433.3 m/min
Answer:
C. 2 mph
Explanation:
speed equals total distance covered in total time of of travel
since,
total distance = 4 miles
time taken = 2 hrs
speed = 4m / 2hrs =2mph
Answer: 0.0146m
Explanation: The formula that defines the velocity of a simple harmonic motion is given as
v = ω√A² - x²
Where v = linear velocity, A = amplitude = 1.69cm = 0.0169m, x = displacement.
The maximum speed of a simple harmonic motion is derived when x = A, hence v = ωA
One half of maximum speed = speed of motion
3ωA/2 = ω√A² - x²
ω cancels out on both sides of the equation, hence we have that
A/2 = √A² - x²
(0.0169)/2 = √(0.0169² - x²)
0.00845 = √(0.0169² - x²)
By squaring both sides, we have that
0.00845² = 0.0169² - x²
x² = 0.0169² - 0.00845²
x² = 0.0002142
x = √0.0002142
x = 0.0146m
If the wagon travels 18.75 m, then the work done on the wagon is
(18.75 m) x (the steady force applied to the wagon all the way, in Newtons) .
The unit is Joules .
