The cyclist moves uniformly in a straight line with an initial speed of 12.5 km / h with an acceleration of 0.4 m / s2. what will be the speed value after 40 s?
Task data: V0 (initial speed at which the cyclist was moving) = 12.5 km / h (3.47 m / s); a (acceleration) = 0.4 m / s2; t (duration of the cyclist’s movement) = 40 s.
The cyclist’s speed after 40 seconds can be determined by the formula: V = V0 + a * t.
Calculation: V = 3.47 + 0.4 * 40 = 19.47 m / s.
Answer: After 40 seconds, the cyclist’s speed will be 19.47 m / s.
