Question

question 1 a bicycle and rider with combined mass of 80 kg accelerate at 2 m/s². what force is propelling them forward? 180 n 160 n 140 n 200 n

Explanation:

Step1: Recall Newton's second - law

$F = ma$

Step2: Substitute given values

$m = 80\ kg$, $a=2\ m/s^{2}$, so $F=80\times2$

Step3: Calculate the force

$F = 160\ N$

Answer:

B. 160 N
