The sled rolled down the hill with uniform acceleration. their speed at the end of the descent is 12 m / s.

The sled rolled down the hill with uniform acceleration. their speed at the end of the descent is 12 m / s. descent time 6 s. with what acceleration did the movement occur if the descent began from a state of rest?

Initial data: the movement of the sled is uniformly accelerated; V (speed of the sleigh at the end of the descent) = 12 m / s; t (time of descent of the sled from the mountain) = 6 s; the descent began from a state of rest and V0 (initial speed of the sleigh) = 0 m / s.

The acceleration with which the sled was moving down the mountain can be expressed from the formula: V = V0 + a * t, whence a = (V – V0) / t = (V – 0) / t = V / t.

Calculation: a = 12/6 = 2 m / s2.

Answer: The constant acceleration of the sled during the descent from the mountain was 2 m / s2.
