Answer:
120 miles
Explanation:
Speed = distance traveled/ time taken.
Distance traveled = speed * time taken
Speed = 40 miles per hour, time = 3 hours.
Distance = 40*3
The train's traveled distance is 120 miles.
Answer:
330 m/s approx
Explanation:
The RMS speed of a gas is proportional to square root of its absolute temperature is
V ( RMS ) ∝ √T
Here V₁ = 200 , T₁ = 23 +273 = 300K , T₂ = 227 +273 = 500 K
Putting the values
200 / V₂ = 
V₂ = 330 m/s approx
No, if the car were moving sideways, then the forces used would be on the horizontal axis. So the weight equation would be extraneous, unless one is determining the net force through an inclined plane
