Answer:
245 N
Explanation:
Force is given by mass × acceleration. The mass is given and we need to determine the acceleration.
The bobsled starts from rest; its initial velocity is 0.0 m/s. After a distance of 6.5 m, its speed is 7.0 m/s
We use the equation of motion:
<em>v</em> is the final velocity, is the initial velocity, <em>a</em> is the acceleration and <em>s</em> is the distance.
The net force is
The answer is B I took the test a while back
The displacement is the distance from the beginning point to the ending point. The time was just to throw you off. If he walks 30m due west, and then 5m due east, his displacement would be 30-5=25m to the west.
