Question 9 of 10

2 Powie
You are riding a bicycle. You apply a forward force of 100 N, and you and the
bicycle have a combined mass of 80 kg. What is the acceleration of the
bicycle?
A. 125 m/s
B. 1.5 m/s2
c. 1.8 m/s?
D. 0.8 m/s​

Answer 1

1.25 m/s^2

Step-by-step explanation:

F = m*a ...... force = mass * acceleration

force = 100 N, mass = 80 kg

100 = 80 * a

100/80 = a = 1.25 m/s^2

Answer 2

The acceleration is 1.25m/s².

Step-by-step explanation:

You have to apply Newton's Second Law which is F = m×a where F represents force, m is mass and a is acceleratipn. Then you have to substitute the following values into the formula :

`f = m * a`

Let F = 100,

Let m = 80,

`100 = 80 * a`

`100 = 80a`

`a = 100 / 80`

`a = 10 / 8`

`a = 1.25`
