Answer:
20 m/s²
Explanation:
Applying,
a = Δv/Δt.................Equation 1
Where a = acceleration of the car, Δv = change in velocity of the car, Δt = change in time.
From the graph,
Given: Δv = (20-0) = 20m/s, Δt = (1-0) = 1 seconds
Substitute these values into equation 1
a = 20/1
a = 20 m/s²
Hence the car's acceleration from 0 to 1 second is 20 m/s²
Answer:
An intermediate swimmer would probably take about four to five minutes, while a trained swimmer could take less than three. The world record is 1:42:00, held by Paul Biedermann. If you are a good swimmer you would swim it easily in 3 and a half minutes.
