Answer:the car was traveling at a speed of 80 ft/s when the brakes were first applied.
Step-by-step explanation:
The car braked with a constant deceleration of 16ft/s^2. This is a negative acceleration. Therefore,
a = - 16ft/s^2
While decelerating, the car produced skid marks measuring 200 feet before coming to a stop.
This means that it travelled a distance,
s = 200 feet
We want to determine how fast the car was traveling (in ft/s) when the brakes were first applied. This is the car's initial velocity, u.
Since the car came to a stop, its final velocity, v = 0
Applying Newton's equation of motion,
v^2 = u^2 + 2as
0 = u^2 - 2 × 16 × 200
u^2 = 6400
u = √6400
u = 80 ft/s
Answer:
It is not well defined.
Step-by-step explanation:
Because set is a collection of well defined objet. And matter contains of solid, liquid and gas
Answer:
Step-by-step explanation:
3000 W = 3 kW
3 kW(4hr/day)(30 day/month) = 360 kWh/month
360 kWh/month($0.15 / kWh) = $54
So about $75 when you add all the taxes and other fees that get added to a typical electric bill.
