Answer: 50 km, 0, 27.78 m/s
Explanation:
Given
Circumference of the track is
Speed of car is
Car drives for
(a)Distance traveled is
(b)displacement of the car
It can be observed that 12.5 is a multiple of 50, that is, 50 km can be interpreted as 4 complete rounds of the track.
Therefore, the displacement of the car is zero.
(c)To convert kmph to m/s, multiply the entity by
The boat traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.
Explanation:
A boat traveling from the dock northward to a 200m mark in the bay in less than 5minutes giving the passengers several more hours to fish is a typical and best example of velocity description.
Velocity is the displacement of a body divided by the time taken.
Velocity =
Displacement is the distance covered in a specific direction. Time is duration of the travel.
Velocity is a vector quantity that has both magnitude and direction. This implies that the value of velocity is recorded with a directional attribute.
We can say velocity is the speed of a body in a given direction
Only the last option gives the displacement of the body and the duration it traveled.

Answer:
Explanation:
Let consider that the person hit the ground in the negative direction. The physical model for the impact is modelled after the Impact Theorem:
The impact is:
The force of impact is derived as follows:
