1. A sports car travelling east at 48.0 m/s passes a trooper hiding at the roadside. The driver uniformly reduces his speed to 22 m/s in 4.10 s
a) Find the magnitude and direction of the car’s acceleration as it slows down
b) Calculate the distance traveled during the 4.10 s time interval
i want know how to get Vaverage=35?
Vaverage = (48 + 22)/2 = 35
To find the average velocity, we need to know the initial velocity and final velocity. In this case, the initial velocity is 48.0 m/s and the final velocity is 22 m/s. To find the average velocity, we can use the formula:
Average velocity (Vaverage) = (initial velocity + final velocity) / 2
Plugging in the given values:
Vaverage = (48.0 m/s + 22 m/s) / 2
Vaverage = (70.0 m/s) / 2
Vaverage = 35 m/s
Therefore, the average velocity (Vaverage) during the given time interval is 35 m/s.
