Which information is necessary to determine an object's speed?
1 answer:
Answer:
1. distance and period of time.
Explanation:
The speed is calculated using the formula
"k" is the speed, "d" is the distance and "t" is the time.
You need distance and time to calculate the speed.
Speed is how fast an object is going. The direction is irrelevant to speed, not to be confused with velocity, which is speed in a given direction.

as it is given that it covers a total distance 1 * 10^2 m
total time taken by it = 13.6 s
now the average speed is given as ratio of total distance and total time
so the average speed will be 7.35 m/s
now if it starts from rest and achieve the final speed as 7.35 m/s
now we can use kinematics
so its acceleration will be 3.68 m/s^2
