4. How fast was a driver going if the car left skid marks that were 32 feet long on dry concrete? (The coefficient of friction i

Monica [59]

Answer:

$v_{o} \approx 31.247\,mph$

Step-by-step explanation:

The deceleration experimented by the car is the product of kinetic coefficient of friction and gravitational constant:

$a = \mu_{k}\cdot g$

$a = (1.02)\cdot \left(32.174\,\frac{ft}{s^{2}} \right)$

$a = 32.817\,\frac{ft}{s^{2}}$

The initial speed is computed from the following kinematic expression:

$v^{2} = v_{o}^{2} - 2\cdot a \cdot \Delta s$

$v_{o} = \sqrt{v^{2}+2\cdot a\cdot \Delta s}$

$v_{o} = \sqrt{\left(0\,\frac{ft}{s} \right)^{2}+2\cdot \left(32.817\,\frac{ft}{s^{2}} \right)\cdot (32\,ft)}$

$v_{o}\approx 45.829\,\frac{ft}{s}$

$v_{o} \approx 31.247\,mph$

Is 5/6 closer to 1, 1/2, or 2 and why?

velikii [3]

1 because 5/6 is almost a whole. It can't be 1/2 because it would have been 3/6. And it's not 2 because it should have been an improper faction

A display case of shirts are marked 10 for $31. If Opal wants to buy 120 shirts, how much will Opal spend (not including tax)?

Lemur [1.5K]

If the shirts all cost the same you would do 120 divided by 10 and that’s 12.you then multiple 31 by 12 and you get 372 so d
