Question

23. A car moving on a straight road accelerates
from a speed of 4.1 m/s to a speed of 6.9 m/s
in 5.0 s. What was its average acceleration?​

Answer 1

Answer:

acceleration = change in velocity ÷ tym

a =( 6.9-4.1)÷5

a = 2.9÷5 = 0.58m/s^2

Answer 2

Answer:

acceleration=change in velocity÷time

acceleration=(6.9-4.1)÷5

acceleration=2.8÷5=0.58m/s^2
