Answer:
Explanation:
Momentum is a concept and is defined as,
Momentum = mass × velocity
So to calculate the momentum of the car
momentum of the car = mass of the car × velocity of the car
So we get,
momentum of the car = 1800 × 30
= 54000 Ns
The angle between incident ray and reflected ray is 60 degree. the value of angle of incidence and angle of reflection is 30 degree
Answer:
its an interaction that can move an object; push or pull makes it or gravity, magnetism
Explanation:
its all in the answer
60 ° is the angle between W- direction and the run direction.
You need the angle betwee S-direction and the run direction. This is 90° - 60° = 30 °.
By geometry you can trace a right triangle, where the S-component is the adyacent side and the run is the hypotenuse.
Then cos 30° = adyacent side / hypotenuse = S-component / run
Then S-component = run * cos 30° = 5.0 km * 0.866 = 4.3 km
Answer: 4.3 km
