A soccer player is running upfield at 10m/s and comes to a stop in 3 seconds facing the same direction. What is his acceleration

Verified Answer :

-10/3m/s2. The formula for acceleration is (Final speed - initial speed)/ time.
Thus, (0m/s - 10m/s)/3s is 10m/s/3s which then can be simplified to /10/3m/s2

Answer:

The acceleration is 3.33 m/s².

Explanation:

Given that,

Velocity = 10 m/s

Time t = 3 sec

We need to calculate the acceleration

Using equation of motion

\(v=u+at\)

Where, v = final velocity

u = initial velocity

t = time

a = acceleration

Put the value into the formula

\(10=0+a\times3\)

\(a=\dfrac{10}{3}\)

\(a=3.33\ m/s^2\)

Hence, The acceleration is 3.33 m/s².
