Question

Sam stops at a red light, after which he starts driving
again at what acceleration must he travel to reach 100 km/h in 2 hours,
supposing that he starts from 0 km/h.

Find the acceleration:

Answer 1

Answer:

43210. 10 . Stop. Start. 1 v1. 2 v2. 3 v3. Time interval. Velocity. Position v2 v1 a ... What velocity does it reach 6.8 s later? v f v i at. 30.0 km/h. (3.5 m/s2)(6.8 s). 1. 1. 00.

Answer 2

Answer:

From the graph we see that at the time interval 2 secs,the distance travelled is 10 m. Hence the velocity(v1) =10/2 = 5m/s. From the graph we see that at the time interval 5 secs,the distance travelled is 25 m. Hence the velocity (v2) =25/5 = 5m/s.
