A cyclist starts from rest and accelerates uniformly at 8 m/s. How far does the cyclist travel in 4 s?
Answer and explanation
Correct answer: D. 64 m
- Step 1: Starting from rest, .
- Step 2: m.
Answer
64 m.
Why not the others: 128 m: the factor is missing. 16 m: time is not squared. 32 m: that is the final speed, not the distance.
