An object is moving in a straight line. At t = 0, its speed is 5.0 m/s. From t = 0 to t = 5.0 s, its acceleration is 2.5 m/s2. From t = 5.0 s to t = 11.0 s, its speed is constant. The average speed over the entire time interval is

Sagot :

Answer:

v1 = a t + v0 = 2.5 * 5 + 5 = 17.5 m/s after 5 sec

v2 = o * 6 + 17.5 = 17.5 m/s after 11 sec

S1 = V0 t + 1/2 a t^2 = 5 * 5 + 1.25 * 5^2 = 56.25 m

S2 = 17.5 * 6 = 105 m

S = 56.3 + 105 = 161 m

Vav = S / t = 161 m / 11 s = 14.6 m/s
