Determine the velocity of the running man with respect to car A.

Physics

<u><em>Answer</em></u>: A) -55 km/h

<u><em>Explanation</em></u>: The running man is traveling at -55 km/hr with respect to Car A. If the man were standing still, the car would be passing at 50. Since he is traveling at 5 in the opposite direction, that direction is positive, to him. His velocity now adds to the car velocity (50 + 5), but negative to account for the opposite direction.

Hope this helps!

A competitive go-cart driver is traveling at a speed of 32m/s. He sees a caution flag go up and slows down at a rate of -1.5 m/s
djyliett [7]

Answer:

His final velocity is 15.8 m/s.

Step-by-step explanation:

Given:

Initial velocity of the driver is, u=32 m/s

Acceleration of the driver is, a=-1.5 m/s²

Time taken to reach final velocity is, t=10.8 s.

The final velocity is given using the Newton's equations of motion as:

v=u+at, where, v is the final velocity.

Now, plug in the given values and solve for v.

v=32-1.5(10.8)\\v=32-16.2=15.8\textrm{ m/s}

Therefore, his final velocity is 15.8 m/s.

Which statement correctly explains scientific theories?
Elan Coil [88]
<span>Scientific theories are tested and proven over time; they are then considered scientific laws.

Sometimes however, they are proven wrong, and so they do not become laws
