Xander's friend Corey has a skateboard that he rides at
Newton's Skate Park. What net force would have to act on
Cory who has a mass of 60 kg for him to have an acceleration
of 1 m/s??

648N

Step-by-step explanation:

Fnet = Fapp + Fg

Fapp = applied force = ma

Fg = gravitational force = mg

Fn = ma + mg

Fn = m ( a + g )

Where m = 60kg, a = 1m/s^2 and

g=9.8m/s^2

Fn = 60 ( 1+9.8)

Fn = 60 × 10.8

Fn = 648N

it would open into a square depending on the type of envelope i’m not sure about the second part
