Answer:25.61 m/s
Explanation:
Given
truck is moving eastbound with a velocity of 16 m/s
Velocity of truck
SUV is moving south with a velocity of 20 m/s
Velocity of SUV in vector form
Velocity of truck relative to the SUV
Magnitude of relative velocity is
λ - wavelength, c - the speed of light, f - frequency
The wavelength of these waves is 1.5 km.
Answer:
Velocity of the car at the bottom of the slope: approximately .
It would take approximately for the car to travel from the top of the slope to the bottom.
Explanation:
The time of the travel needs to be found. Hence, make use of the SUVAT equation that does not include time.
- Let
denote the final velocity of the car.
- Let
denote the initial velocity of the car.
- Let
denote the acceleration of the car.
- Let
denote the distance that this car travelled.
