Answer:

1 \frac{m}{s^{2} }

Explanation:

Hello,I think I can help you with this

the acceleration is the change in the speed, in a given time. it can be calculated

acceleration(a) =\frac{speed_{f} -speed_{i} }{time}\\\\

Step 1

let

\\speed_{f}=100\ \frac{m}{s} \\speed_{i}=90\ \frac{m}{s} \\time=10\ seconds\\

put the values into the equation

acceleration(a) =\frac{100\ \frac{m}{s} -90\ \frac{m}{s} }{10\ sec}\\\\acceleration(a)=\frac{10 \frac{m}{s} }{10\ seconds}\\acceleration(a)=1 \frac{m}{s^{2} }

Have a nice day

An automobile with 0.500 m radius tires travels 80,000 km before wearing them out. How many revolutions do the tires make, negle
Zinaida [17]

Answer:

n = 25,464,790.89 revolutions

The tires have made 25,464,790.89 revolutions

Explanation:

Given;

Radius of tires r = 0.5 m

Total distance travelled d = 80,000 km = 80,000,000 m

1 revolution = 2πr

Total distance d = number of revolutions n × 2πr

d = n×2πr

d = 2πnr

Making n the subject of formula;

n = d/2πr

Substituting the given values;

n = (80,000,000)/(2×π×0.5)

n = 25,464,790.89470 revolutions

n = 25,464,790.89 revolutions

The tires have made 25,464,790.89 revolutions

A centrifuge is a device that rotates an object to produce an acceleration many times that of gravity Pilots are trained in such
Leviafan [203]

Answer:

ω = 0.571 rad/s

Explanation:

given data

radius = 30 m

solution

we take here g = 9.8 m/s²

and g is express as

g = r × ω²     ....................1

put here value and we get

9.8 = 30 × ω²

solve it we get

ω = 0.571 rad/s
