Answer:

37 mph

Step-by-step explanation:

Sum of forces on the car in the y direction:

∑F = ma

N − mg = 0

N = mg

Sum of forces on the car in the x direction:

∑F = ma

-Nμ = ma

-mgμ = ma

-gμ = a

Given μ = 0.75 and g = 32 ft/s²:

a = -(32 ft/s²) (0.75)

a = -24 ft/s²

Use kinematics to find the initial velocity.

v² = v₀² + 2aΔx

(0 ft/s)² = v₀² + 2 (-24 ft/s²) (60 ft)

v₀ ≈ 53.7 ft/s

v₀ ≈ 37 mph

What is negative 8 over 12?

Sedaia [141]

That would be $\frac{-8}{12}$ , but it is also equal to just $-\frac{8}{12}$ . You would simplify the $\frac{8}{12}$ part, and you would get $\frac{2}{3}$ , or if you need a decimal, $0.6666...$
But don't forget the negative part, so the answer would be $-\frac{2}{3}$ or $-0.6666...$
