A bike takes 6 s to accelerate from 10 m/s
to 14 m/s. The mass of the bike and its
rider is 90 kg. Find the net force and the
final momentum of the bicyclist.

Respuesta :

Answer:

Explanation:

F = ma = mΔv/Δt = 90(14 - 10) / (6 - 0) = 60 N

p = mv = 90(14) = 1,260 kg•m/s (for bicyclist AND bike together)
