<span> it CAN be negative if you consider the velocity as "vector". It CANNOT if you consider the "numerical" velocity..</span>
B.gold also known as the famous gold foil experiment
Answer:
The planes´s horizontal distance is DH = 13845 meters
Explanation:
We need to get the vector components because we already know the distance and the angle so using the trigonometric identity of Cos(Ф) we can get the horizontal component and if we get the component on x axle like 22000 (m)*Cos(51°) = x so we can find that x = 13845.05 meters
Sin0) is not exactly in the direction of equilibrium position. But the condition of S.H.M. Is restoring force must directed to the equilibrium position in all instant
