The sleigh drove down the slope of a 48m long mountain in 16 seconds. what is the speed of the sleigh at the end of the descent? the movement of the sleigh can be considered uniformly accelerated with an initial speed of 0.
Problem data: L (length of the mountain slope) = 48 m; t (time for the sleigh to roll down the slope) = 16 s; uniformly accelerated motion; V0 (speed of the sleigh before descending) = 0 m / s.
To calculate the speed of a given sleigh at the end of the descent, we use the formula: S = L = (V + V0) * t / 2, whence V = 2S / t – V0.
Calculation: V = 2 * 48/16 – 0 = 6 m / s.
Answer: At the end of the descent, the specified sled had a speed of 6 m / s.
