Question

A car speeds up from 18.54 m/s to 29.52 m/s in 13.84 s. The acceleration of the car is:

Answer 1

Answer:

.7934$m/s^{2}$

Explanation:

Acceleration = change in velocity / change in time

A = 10.98$m/s$ / 13.84$s$

A = .7934$m/s^{2}$

Answer 2

Answer:0.8 m/s^2

Explanation:

initial velocity(u)=18.54m/s

Final velocity(v)=29.52m/s

Time(t)=13.84 sec

Acceleration =(v-u)/t

acceleration =(29.52-18.54)/13.84

Acceleration =10.98/13.34

Acceleration=0.8 m/s^2
