| **The sleds slide along the ice path with an initial speed of 8 m / s, and for each second their speed decreases by 0.25 m / s. how long will the sled stop?**

To calculate the braking time of a given sled, we apply the formula: t = (V – V0) / a.

Values of variables: V – final speed of the sled (V = 0 m / s); V0 – speed at the beginning of sliding (V0 = 8 m / s); a – sled acceleration (a = -0.25 m / s2).

Let’s make a calculation: t = (V – V0) / a = (0 – 8) / (-0.25) = 32 s.

Answer: The sled slid along the ice path for 32 seconds.
