Question

If a car has a constant acceleration of 4 m/s2, starting from rest, how far has it

traveled after 5 seconds?

Answer 1

50m

Step-by-step explanation:

S = 0 x 5 + 1/2 4.(5)^2

S = 0 + 1/2 x 4 x 25

S = 1/2 x 4 x 25

S = 2x25

S = 50m

Answer 2

650m

Step-by-step explanation:

Total distance =S1+S2+S3=50+500+100=650m.
