tatuchka [14]3 years ago

6 0

Answer:

Explanation:

ACCELERATION = <u>CHANGE IN VELOCITY </u>

TIME TAKEN

∴ a = <u>25 - 0 </u>

10.5

∴ a = <u> 50 </u>

by using f = ma,

we get , f = 3950 × <u>50 </u>

∴ A FORCE OF 9404.8 N IS NEEDED TO ACCELERATE A BUS OF 3950 KG.

17. Matthew has a piece of wood with mass of 278 g and a volume of 375 cm^3. What is the wood’s density? a. Step 1: Formula ____

Keith_Richards [23]

Answer:

Density =0.74 $g/cm^{3}$

Explanation:

Step 1: Formula

$Density=\frac{Mass}{Volume}$

Step 2: Data

m=278 g

v=375 $cm^{3}$

Step 3:Solve

d= $\frac{278}{375}$ $g/cm^{3}$

d=0.74 $g/cm^{3}$

If a 0.08 kg cell phone falls off a table at 15 m/s, then what is its kinetic energy right before it hits the ground?

Mariana [72]

The kinetic energy of the phone right before it hits the ground is 9J.

<h3>Kinetic energy of the phone</h3>

The kinetic energy of the phone right before it hits the ground is calculated as follows;

K.E = ¹/₂mv²

where;

m is mass of the phone
v is velocity of the phone

K.E = ¹/₂(0.08)(15)²

K.E = 9 J

Thus, the kinetic energy of the phone right before it hits the ground is 9J.
