Issac and Blaise decide to race. They both start at the same position at the same time. Issac runs at 2m/s but decides to take a

FromTheMoon [43]

Let the Blaise runs for time "t" to complete the race

so the total distance he moved is given by

$d_1 = 1* t$

Now Issac runs for time t = "t - 2*60"

because it took rest for 2 minutes

$d_2 = 2*(t - 120)$

now it is given that Blaise wins by 10 m distance

$d_1 - d_2 = 10$

$1* t - 2*(t - 120) = 10$

$t - 2t + 240 = 10$

$t = 230 s$

now the distance moved by Blaise is given by

$d_1 = 1*230 = 230 m$

vagabundo [1.1K]

Answer:

$\boxed {\boxed {\sf D. \ -11 \ m/s^2}}$

Explanation:

Acceleration can be found by dividing the change in velocity by the time.

$a=\frac{v_f-v_i}{t}$

where Vf is the final velocity, Vi is the initial velocity, and t is the time.

Since the car came to a complete stop, it's final velocity was 0 meters per second.

The initial velocity was 22 meters per second.

The time was 2.0 seconds.

$v_f=0 \ m/s\\v_i=22 \ m/s\\t= 2.0 \ s$

Substitute the values into the formula.

$a=\frac{0 \ m/s-22 \ m/s}{ 2.0 \s }$

Subtract in the numerator first.

0 m/s- 22 m/s = -22 m/s

$a=\frac{-22 \ m/s}{2.0 \ s}$

Divide.

$a= -11 \ m/s^2$

The acceleration of the car was -11 meters per square second. The negative acceleration indicates slowing down/stopping.
