<u><em>Explanation:</em></u>
This exposes the individual to danger. <em>Remember</em>, the Newton Law of motion which says that an object under the state of rest will remain in that state (inertia) unless when acted upon by an external force.
In this scenario, standing at the back of the pickup truck presents danger especially if the truck suddenly stops; this individual would experience an upward thrust due to inertia that may disbalance him.
Answer:
Magnitude = 26 m
Direction = eastward
Explanation:
Given that a football coach walks 24 meters eastward, then 12 meters westward, then 36 meters eastward, and finally 22 meters westward. What is the magnitude and direction of the displacement?
Let eastward be positive and westward be negative.
Magnitude = 24 - 12 + 36 - 22
Magnitude = 60 - 34
Magnitude = 26
Since the answer is positive, the direction will be eastward.
Therefore,
Magnitude = 26 m
Direction = eastward
<u>Answer:</u>
Chipmunk's average acceleration during the 2.07 s time interval = 0.1256
<u>Explanation:</u>
We have equation of motion, v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.
In this case we need to find acceleration value, we have initial velocity = 1.47 m/s, final velocity = 1.73 m/s and time taken = 2.07 seconds.
Substituting
1.73 = 1.47 + a * 2.07
a = 0.1256
Chipmunk's average acceleration during the 2.07 s time interval = 0.1256
Point a because point a is the highest at potential energy converting into the highest kinetic energy.
