A car drives on a highway with a speed of 68mi/hr. What is the speed in km/hr?

Physics
1 answer:
spin [16.1K]3 years ago
3 0

Answer:

Speed in km/hr will be 109.412 km/hr

Explanation:

We have given speed of the car on a highway = 68 mi/hr

We have to find the speed in km/hr

For this first we have to change mi to km

We know that 1 mile = 1.609 km

Speed is the ratio of distance and time

So 68 mi/hr =68\times 1.609km/hr=109.412km/hr

So the speed in km/hr will be 109.412 km /hr

serious [3.7K]
Momentum is a term used to quantify the motion of an object has. It is calculated as the the product of the object's mass and the velocity. It is expressed as:

Momentum = m x v
Momentum = 50 kg x 5 m/s
Momentum = 250 kg m/s

Therefore, the correct answer is the last option.

A wave traveling in water has a frequency of 250 Hz and a wavelength of 6.0m. What is the speed of the wave?
vladimir2022 [97]
Since you are looking for the speed, you need to rearrange the formula which is f = speed / wavelength. That should give you speed = f (wavelength.) All you need to do next is to substitute the value to the following equation.  speed = 250 Hz (6.0m) that should leave you with 1500 m/s which is very fast.
