Answer:
170 N
Explanation:
Since Force F = ma were m = mass = 85 kg and a = acceleration = 2.0 m/s².
So the net force on the bicycle is
F = ma = 85 kg × 2.0 m/s² = 170 N
Can't really plot a graph here for question 1.
2a) The car speeds up from A to B. The car travels at a constant speed from B to C. The car slows down to a stop from C to D.
b) From the graph, at 10 seconds, the car is moving at 20 m/s.
A. logic, would be your answer i believe!
The distance decreases as the time increases
