a bicycle wheel has 77cm in diameter and makes revolution per second .find the speed of the bicycle in m/s

for each revolution, it goes PI*diameter on the ground.

speed: PI*diameter/time

time is one second.

speed: PI*.77 m/s

To find the speed of the bicycle in m/s, we can use the formula:

speed = circumference of the wheel x number of revolutions per second

First, let's calculate the circumference of the wheel:

Circumference = π x diameter

Given that the diameter of the wheel is 77 cm, we can plug in the values and calculate the circumference:

Circumference = 3.14 x 77 cm

Next, we need to convert the circumference from centimeters to meters since we want the answer in m/s. Since 1 meter = 100 centimeters, we can divide the circumference by 100:

Circumference = (3.14 x 77 cm) / 100

Now, let's calculate the number of meters the wheel covers in 1 revolution:

1 revolution = circumference of the wheel

To convert this into meters, we divide the circumference by 100:

1 revolution = (3.14 x 77 cm) / 100

Finally, to find the speed of the bicycle in m/s, we multiply the number of revolutions per second with the distance covered in 1 revolution:

speed = (3.14 x 77 cm / 100) x (number of revolutions per second)

Plug in the number of revolutions per second, and you will have the speed of the bicycle in m/s.
