Answer:

The answer is:    

150 m

Explanation:

find acceleration first.

Vf = at + Vi

20 = a(15) + 0

a = 1.33m/s^2

x = 1/2at^2

x = 1/2 (1.33) (15)^2

x = 149.625m or round it to 150m

hope this helps

Answer:

1.33

Explanation:

We know

speed =<u>distance</u><u> </u><u>travelled</u>

time taken

so here distance travelled is 20.0 m/s

and time taken is 15.0s

now simplify

s=20.0/15.0

=4/3

=1.33

hope you understood it!

nataly862011 [7]

Answer:

40 cm

Explanation:

We are given that

Load=800 N

Effort=200 N

Load  distance=10 cm

We have to find the effort distance.

We know that

load\times load\;distance=Effort\times effort\;distance

Using the formula

800\times 10=200\times effort\;distance

Effort distance=\frac{800\times 10}{200}

Effort distance=\frac{8000}{200}

Effort distance=40 cm

Hence,  the effort distance will be 40 cm.

What is the force required accelerate a 5.0 kg object at 3.0m/s^ 2?
NeX [460]
The equation to find force is f=ma. So, if you plug in the information that you have you'll get F=5x3 and that'll equal F=15N

A vinyl record is played by rotating the record so that an approximately circular groove in the vinyl slides under a stylus. Bum
AleksandrR [38]

Answer:

Hits per second=199 hit/s

Explanation:

#Given the angular velocity, \omega=33\frac{1}{3} rev/min , radius of the record r=0.1m and the distance between any two successive bumps on the groove as d=1.75mm.

The linear speed of the record in meters per second is:

v=\omega r=33\frac{1}{3}\times\frac{2\pi}{60}\times 10\times 10^{_2}\\\\=0.3843m/s\\

#From v above, if the bumps are uniformly separated by 1m, then the rate at which they hit the stylus is:

Hits/second=v/d    \ \ \ \ d=1.75mm\\\\=0.3483/0.000175\\\\=199.0385714\approx 199

Hence the bumps hit the stylus at around 199hit/s
