Marcy and joe are racing on their bikes. Starting from rest, if Marcy has an average acceleration of 5.7 m/s? for the first five seconds how fast was he traveling at the end of those five seconds?
To find out how fast Marcy was traveling at the end of the five seconds, we can use the equation of motion:
v = u + at
Where:
v is the final velocity (what we want to find)
u is the initial velocity (which is zero since they started from rest)
a is the average acceleration (given as 5.7 m/s²)
t is the time (given as 5 seconds)
Plugging in the values, we get:
v = 0 + 5.7 * 5
Calculating this, we get:
v = 28.5 m/s
Therefore, Marcy was traveling at a speed of 28.5 m/s at the end of the five seconds.
