Answer:
5.71 m/s ;
20 m/s
Explanation:
Blue car:
At time, t = 0 ; Initial position = 20 m
Final position, = 60m after 4 seconds
The velocity = change in distance / change in time.
Velocity of blue = (60 - 20)m ÷ ((4 + 3) - 0),
Velocity of blue car = 40 / 7
= 5.71 m/s
Red car:
Initial Position = 0 ; final Position = 60
Time taken = 3 seconds
Velocity of Red car = (60 - 0)m ÷ 3
Velocity of Red car = 60 / 3
= 20 m/s
The volume increases, but the surface area remains the same
We actually cant, really. Black Holes are really very powerful and don't just happen in some random place in the cosmos. We have got shots of Black holes that you cannot even see, but all the other big black holes that look like something straight of a sci-fi movie that look real, are really just photo- shopped. good question. Hope This Helped.
<span>An automobile with a mass of 1450 kg is parked on a moving flatbed railcar; the flatbed is 1.5 m above the ground. The railcar has a mass of 38,500 kg and is moving to the right at a constant speed of 8.7 m/s on a frictionless rail...

Your speed is one of the only factors that has an effect on both your thinking distance and braking distance. Put simply, the faster you are going, the greater the distance travelled before you apply the brakes (thinking distance) and the vehicle comes to a complete stop (braking distance).
