If a toy plane is spinning on a string 1.87 meters off the ground and the string is .5m long how long does it take to make 10 revolutions?

Don't you need either angle of the string or mass of plane or velocity to answer this question?

To calculate the time it takes for the toy plane to make 10 revolutions, we need to consider two factors: the length of the string and the speed at which it rotates.

The circumference of a circle can be calculated using the formula C = 2πr, where C represents the circumference and r represents the radius. In this case, the radius is equal to the length of the string, which is 0.5 meters. Therefore, the circumference of the circle that the toy plane is spinning in is 2π(0.5) = π meters.

To determine the total distance traveled during 10 revolutions, we need to multiply the circumference of the circle by the number of revolutions: 10 (revolutions) * π (circumference) = 10π meters.

Next, we need to find the speed at which the toy plane is rotating. Since we don't have any information about the speed, we'll assume it to be constant. Let's say the toy plane takes t seconds to complete one revolution. Therefore, the time taken to complete 10 revolutions will be 10t seconds.

Now, we need to find the relationship between the distance traveled and the time taken. The formula for speed is given by the equation: speed = distance/time. Rearranging the equation to solve for time, we get: time = distance/speed.

Substituting the values we have, the time it takes to complete 10 revolutions can be calculated as follows:

time = (10π meters) / speed

Since we don't have the value for speed, it cannot be determined exactly without additional information. If you're given any details about the speed or provided with an equation or formula to calculate it, I'd be happy to help further.
