Answer:
The acceleration is 7m/s^2
Step-by-step explanation:
Given
[tex]u = 0m/s[/tex] -- Initial Velocity
It is 0 because the person starts from a standstill
[tex]v = 35m/s[/tex] -- final velocity
[tex]t = 5s[/tex] -- time
Required
Determine the acceleration
This is calculated using Newton's first equation of motion
[tex]v = u + at[/tex]
Substitute values for v, u and t
[tex]35 = 0 + a*5[/tex]
[tex]35 = 0 + 5a[/tex]
[tex]35 = 5a[/tex]
Divide both sides by 5
[tex]\frac{35}{5} = a[/tex]
[tex]7 = a[/tex]
[tex]a = 7[/tex]
Hence, the acceleration is 7m/s^2
