U = 0, initial vertical velocity
v = 60 mph = 88 ft/s

Ignore air resistance and take g = 32 ft/s².
It t = time to attain 60 mph, then
(88 ft/s) = (32 ft/s²)*(t s)
t = 88/32 = 2.75 s

Answer: 2.75 s

The speed of light inside a medium is (2.0 x 10^8m/s) What is the index of refraction (n) of the medium?
kondor19780726 [428]

Answer:

Refractive index of a medium = Speed of light in vacuum/Speed of light in a medium

1.5 = 3 x 108 / Speed of light in medium

Speed of light in the medium = 3 x 108 /1.5

= 2 x 108 m/s.

How far will 20 N of force stretch a spring with a spring constant of 140 N/m?
densk [106]

Answer:

0.143 m

Explanation:

The relationship between force applied on a string and stretching of the spring is given by Hooke's law:

F=kx

where

F is the force exerted on the spring

k is the spring constant of the spring

x is the stretching of the spring from its equilibrium position

In this problem, we have:

F = 20 N is the force applied on the spring

k = 140 N/m is the spring constant

Solving for x, we find how far the spring will stretch:

x=\frac{F}{k}=\frac{20}{140}=0.143 m

An electron travels 1.92 m in 4.47 × 10−8 s. How fast is it traveling?<br> Answer in units of m/s.
malfutka [58]
Speed = (distance covered) / (time to cover the distance).

             =  (1.92 meters)  /  (4.47 x 10⁻⁸ second)

            = 42,950,000 meters/second  (rounded to the nearest 10,000 m/s)

That's about  96.1 million miles per hour, or about 14% of the speed of light.
