A cyclist is riding downhill with an acceleration of 0.3 m / s. What speed will the cyclist get in 20 s if his initial speed is 4 m / s?

These tasks: a (acceleration with which the cyclist rides down the mountain) = 0.3 m / s2; t (duration of the cyclist’s movement) = 20 s; V0 (initial speed) = 4 m / s.
The speed that the cyclist will receive in 20 seconds is determined by the formula: V = V0 + a * t.
Calculation: V = 4 + 0.3 * 20 = 10 m / s.
Answer: After 20 seconds of movement from the mountain, the speed of the cyclist will be 10 m / s.
