Question

Kirima and her brother Yoskolo make all sorts of creations with the ice around them. Today they decide to make an ice sled so that they can race each other down the 18-degree slope they are playing on. The coefficient of kinetic friction of ice on ice is low (typically 0.03), so neglecting friction, what is the acceleration of the children's ice sleds as they slide down the hill? Select one: ОА. 3.03 m/s2 ов. 2.94 m/s2 O c. 4.15 m/s2 OD. 1.28 m/s2

Answer 1

Option A is correct!.

free body diagrom of Creation of kinima & her brother, 9-9.81 m/s2 2 mg smigo 18 mg cosige mg Neglecting friction, g = acceleration due to granity. i from Newton's second law, Net Force in direction mass Xaccele. motion = accederation = SM 18° mg m .: acceleration = g sinis - 9.81 Sin 18 m/s2 3.03 m/s² a → option A is correct
