For 1 minute, the trolley rolls downhill with an acceleration of 15cm / s². What speed will it acquire during this time if the initial speed of the trolley is zero?
Task data: t (time during which the trolley rolls downhill) = 1 min (in SI t = 60 s); a (trolley acceleration) = 15 cm / s2 (in SI a = 0.15 m / s2); V0 (initial speed) = 0 m / s.
The speed that the trolley will acquire in 1 minute of accelerated movement is determined by the formula: V = V0 + a * t.
Let’s calculate: V = 0 + 0.15 * 60 = 9 m / s.
Answer: After 1 minute, the speed of the trolley will be 9 m / s.
