An car initially at rest experiences an acceleration of 1.00 m/s² for 6.30 s then travels at that constant velocity for another 9.70 s. What is the magnitude of the object’s average velocity over the 16 s interval?

Question

An car initially at rest experiences an acceleration of 1.00 m/s² for 6.30 s then travels at that constant velocity for another 9.70 s. What is the magnitude of the object’s average velocity over the 16 s interval?

Step 1

Average velocity is :

Total displacement
Average velocity
Total time taken
From, 0 to 6.3 seconds, the car experiences an acceleration,a = 1.00 m/s2
Initial velocity, u= 0
Therefore, the velocity at the end of 6.3s is, v, = u+ at = 6.3m/s
at2
Thus, displacement s = ut +
2
0, s =0+x (6.3)2
2
or, S 19.84 5m

Step 2

Further,...

From, the next 9.7 seconds , the car
experiences zero acceleration
Initial velocity in this case is v
6.3m/s
at2
Thus, displacement s, = vt

0r, s2 (6.3) x (9.7)0
or, s 61.1 1m
