Step-by-step explanation:

A new car that sells for $19,000 depreciates (decreases in value) 21% each year. What is the decay factor, b? 0.79 0.21 79 21

Answers

Answer: 0.79

Step-by-step explanation:

Given: The cost price of car = $19,000

The rate of depreciation = 21 % = 0.02

The exponential decay equation (depreciation) is given by :-

y=Ab^x, where A is the initial amount and b is the decay factor for x years such that b=(1-r), where r is the rate of decay.

If we substitute the value of r , we get

The decay factor =b = (1-0.21)=0.79
The decay factor is 0.21 ((:

Answer:

Answer is below. Hope this helps you!

Step-by-step explanation:

(i)v = u + at

(ii) s = ut + 1/2 *at²

(iii)2as = v²-u²

Examples:

A train starting from rest attains a velocity of 72km/h in 5 minutes. Assuming that the acceleration is uniform, find (i) the acceleration and  (ii)  the distance travelled by the train for attaining this velocity.

72km/h = 20m/s

(i) use v= u+ at

20 = 0 + a*300

20 = 5a

20 / 300= a

1/15 ms² = a

to find distance

use 2as= v²-u²

2 *1/15 * s = (20) - 0²

2/15s = 400

s = 400 * 15/2

s = 3000m = 3 km

a car accelerates with a uniform acceleration of 1m/s². it starts with a  velocity of 18km/h and reaches 36 km/h in 5 seconds find the distance travelled.

18 km /h = 5m/s

36km/h = 10m/s

use - s= ut + 1/2at²

s = 5 * 5 + 1/2 * 1 * (5)²

s = 25 + 25/2

s = 37.5 meters

Answer:

It is described in terms of displacement, distance, velocity, acceleration, time and speed. Jogging, driving a car, and even simply taking a walk are all everyday examples of motion.

...

The three equations are,

v = u + at.

v² = u² + 2as.

s = ut + ½at²

If one vehicle is going 20 mph and another is going 60 mph, the one going 60 mph has __9____ times the force at impact as the one going 20 mph.

Answers

Answer:

Assuming that both vehicles have the same mass: It´s 9 times

Step-by-step explanation:

You can use the formula for kinetic energy which is: K = (mv^2)/(2)

We can calculate two different values for each speed. We assume that the mass is "m"

K_1 = (m(20)^2)/(2) = (400m)/(2) = 200m\n\nK_2 = (m(60)^2)/(2) = (3600m)/(2) = 1800m\n\n

As you can see the K2 is 9 times bigger than K1
