One dimensional motion of a tortoise

AI Thread Summary
A tortoise runs at a speed of 0.10 m/s, while a hare runs 20 times faster, at 2.0 m/s. In a race, the hare takes a 2.0-minute break, allowing the tortoise to win by 20 cm. The tortoise's distance covered in time t is represented by the equation 0.10*t meters. The hare's distance, accounting for the rest period, is expressed as 20*0.10*(t-120) meters. To determine the race duration and length, the equation derived from the winning condition is 20*0.10*(t-120) = 0.10*t - 0.2. Solving this equation will provide the total time of the race and the distance covered.

can anyone help me with this problem please--

A tortoise can run with a speed of 0.10 m/s and a hare can run 20 times as fast. in a race they both start at the same time but the hare stops to rest for 2.0 minutes. the tortoise wins by 20 cm.

how long does the race take?
what is the length of hte race?

I guess the totoise runs 0.10*t and the hare 20*0.10*(t-120) meters. One little first degree equation...
 
The distance the tortoise covers in t seconds is 0.10*t meters and the distance the hare covers is 20*0.10*(t-120) meters as Sonty said. However, the condition that "the tortoise wins by 20 cm" means that, if t is the time when the tortoise crosses the finish line, then 20*0.10*(t-120)= 0.10*t- 0.2. That's the equation you need to solve.
 
thank u both
 
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
Thread 'Beam on an inclined plane'
Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
