Question

A 65kg bicyclist (including the bicycle), initially at rest, pedals to the right, generating 200N of force for 6s. During this time, they experience 40N drag. Neglect any

additional friction impeding their motion. Their net force on the bicycle is
A. 240 N
B. 160 N
C. 305 N

Answer 1

The net force on the bicycle exerted by the 65kg bicyclist, after accounting for the 40N drag, is 160 N (Option B).

Step-by-step explanation:

The student's question pertains to the net force that the bicyclist produces while pedaling in the presence of drag. To calculate the net force exerted on the bicycle by the bicyclist, we subtract the drag force from the force generated by pedaling. This is done by applying Newton's second law which indicates that the net force on an object is the product of mass and acceleration (F = m * a).

The given values are a pedaling force of 200N and a drag force of 40N. The net force (Fnet) can be calculated as:

Fnet = pedaling force - drag force
Fnet = 200N - 40N
Fnet = 160N

Therefore, the correct answer is B. 160 N.

Answer 2

A .240N is the correct answer
