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:
$1632
Step-by-step explanation:
Hourly pay for Diego = $10.20
Weekly hours = 40 Hours
Basic earning = 10.20 × 40 = $408
Overtime pay = 15 × Hourly rate = 15 × 10.20 = $153
Total overtime = 8 hours
Overtime earning = 153 × 8 = 1224
Total earning for the week = 408 + 1224 = $1632
First you measure the volume then use multiplication
We have
To simplify it we can divide numerator and denumerator by the same number (the greatest possible is the best)
- its the simples form..
