Two physics students are trying to detemine the
instantaneous speed of a bicycle 5.0 m from the
start of a 1000 m sprint. It takes 4s to travel 10m. What is the instananeous speed at the 5m mark? acceleration is constant.
(5m mark is 10 m as they start at -5m)
U=initial speed (U= 0m/s)
Note. This is the first thing ive tried since joining year 11 so i am quite a novice and may have just made a stupid error
The Attempt at a Solution
But the answers say it 3.5m/s.
