Answer:
b,c
Explanation:
Velocity refers to the rate of change of position with respect to time and acceleration refers to the rate of change of velocity with respect to time. Both velocity and acceleration are vector quantities
While the line of children is rotating, <u>the player at the front of the line has the smallest linear velocity and all the children have the same angular acceleration.</u>
The unit for power is Watts. the newton is a unit for force. joules for energy and meters for distance
B - speed and direction are combined in another quantity, called velocity. It can be thought of as its speed in a particular direction. Speed is the corresponding scalar quantity, because it does not have a direction.
The given velocity is 465 m/s.
Part a.
Answer: 1674 km/h
Part b.
Answer: 40,176 km/day.
