In a race, a runner traveled 12 meters in

Nastasia [14]

Since it is a race, the runner start from rest, so we can use the Velocity Hourly Equation to describle yours moviment.

$S=S_{o}+V_{o}t+ \frac{at^2}{2} \\ S=\frac{at^2}{2}$

Entering the unknowns, we have:

$S=\frac{at^2}{2} \\ 12*2=a*4^2 \\ \boxed {a=1.5m/s^2}$

Number 2

If a car has a linear acceleration of 1.8m/s^2 and the radius of its wheels is 0.33m, what is the angular acceleration of the wh

daser333 [38]

Answer:

5.45rad/s^2

Explanation: Given that

a = 1.8m/s^2

r = 0.33m

a= αr

1.8 = α × 0.33

1.8 = 0.33α

α = 1.8/0.33

α = 5.45rad/s^2
