A bus slows with constant acceleration from 24.0 m/s to 16.0 m/s and moves 50.0 m in the process. (a) How much further does it t

navik [9.2K]

Answer:

(a) Bus will traveled further a distance of 40 m

(b) It will take 7.5 sec to stop the bus

Explanation:

We have given initial velocity of the bus u = 24 m/sec

And final velocity v = 16 m/sec

Distance traveled in this process s = 50 m

From third equation of motion we know that $v^2=u^2+2as$

$16^2=24^2+2\times a\times 50$

$a=-3.2m/sec^2$

(a) Now as the bus finally stops so final velocity v = 0 m/sec

So $v^2=u^2+2as$

$0^2=24^2-2\times 3.2\times s$

s= 90 m

So further distance traveled by bus = 90-50 =40 m

(b) Now as the bus finally stops so final velocity v= 0 m/sec

Initial velocity u = 24 m/sec

Acceleration $a=-3.2m/sec^2$

So time $t=\frac{v-u}{a}=\frac{0-24}{-3.2}=7.5sec$

Provide the following information for each of the three types of radiations from naturally radioactive materials. Be sure to inc

scoundrel [369]

Alpha radiation: Particles. Each alpha particle is a little bundle of 2 protons and 2 neutrons ... identical to the nucleus of a Helium atom.

Charge . . . +2 elementary charges

Mass . . . 4 Atomic Mass Units

Relative penetrating power . . . low

The effect an electric field would have on it . . . Since the alpha particle has a positive charge, it's repelled by other positive charges, and attracted toward negative charges.

Beta radiation: Particles. Each beta particle is an electron.

Charge . . . -1 elementary charge

Mass . . . 0.00055 AMU

Relative penetrating power . . . medium

The effect an electric field would have on it . . . repelled by other negative charges, and attracted toward positive charges.

Gamma radiation: electromagnetic wave, verrrrry short wave, high frequency

Charge . . . electromagnetic wave, no charge

Mass . . . electromagnetic wave, no mass

Relative penetrating power . . . high

The effect an electric field would have on it . . . electromagnetic wave, no effect
