A person Drove from 8am Tuesday to 5pm Wednesday. Total drive 396 miles. He have lunch for 30 min on Tuesday and sleep overnight
r-ruslan [8.4K]

Answer:

average speed = 18 miles / hour

Explanation:

Given data

drive = 396 miles

time = 8 am Tuesday to 5 pm Wednesday = 33 hours

lunch = 30 min Tuesday  + 30 min Wednesday = 60 min = 1 hour

sleep = 7 pm Tuesday to  5 am Wednesday = 10 hours

to find out

average speed

solution

we know that he take total time = 33 hours and he took rest + luch = ( 1 + 10 hours)

so total travel time is = 33 - 11 = 22 hours

so

average speed = distance / time

average speed = 396 / 22

average speed = 18 miles / hour

A sprinf has a potential energy of 84.08 J and a constant of 342.25 N/m. How far it been stretched? Use potential energy elastic
valina [46]

The spring has been stretched 0.701 m

Explanation:

The elastic potential energy of a spring is the potential energy stored in the spring due to its compression/stretching. It is calculated as

E=\frac{1}{2}kx^2

where

k is the spring constant

x is the elongation of the spring with respect to its equilibrium position

For the spring in this problem, we have:

E = 84.08 J (potential energy)

k = 342.25 N/m (spring constant)

Therefore, its elongation is:

x=\sqrt{\frac{2E}{k}}=\sqrt{\frac{2(84.08)}{342.25}}=0.701 m
