Answer #1


m=800kg V=9.5 mis a=3.5 m/s2 Power = FxV =(mxa) v = 800x3.5) 9.5 IP = 26600 W - 26600 Please note that this is the instantane

    A driver operating a vehicle at a speed of 25.0 m/s intends to pass a second vehicle 2.00 km ahead traveling in the same direction with a speed of 30.0 m/s. The driver of the first vehicle accelerates at a uniform rate to pass the second vehicle, and does so after traveling 4.00 km. Thus, whereas the first (rear) vehicle traverses 4.00 km, the second (front) car only travels 2.00 km, when it is passed. If the driver of the...
