The sled went down the mountain at a speed of 15m / s in 4 seconds, determine the acceleration.

Task data: V2 (speed of the sled at the end of the descent) = 15 m / s; t (duration of descent) = 4 s.

The acceleration of the sled under consideration can be calculated by the formula: a = (V2 – V1) \ t.

Let’s perform the calculation: a = (15 – 0) \ 4 = 3.75 m / s2.

Answer: The sled under consideration descended from the mountain with an acceleration of 3.75 m / s2.
