Answer:
The distance and average speed are 54.79 m and 10.85 m.
Explanation:
Given that,
Speed = 21.7 m/s
Time = 5.05 s
(a). We need to calculate the distance
Firstly we will find the acceleration
Using equation of motion
Where, v = final velocity
u = initial velocity
t = time
Put the value in the equation
Now, using equation of motion again
For distance,
The distance is 54.79 m.
(b). We need to calculate the average speed during this time
Where, D = total distance
T = time
Put the value into the formula
Hence, The distance and average speed are 54.79 m and 10.85 m.
