A 53kg skateboarder pushes on the ground with -351N of force to set himself moving. How fast will the skateboarder accelerate?

Answer 1

Hello, Iy,

Newton's Second Law: F = MA

351N = 53kg*A

A Newton has units of kg*m*s^-2

351 kg*m*s^-2 = 53kg*A

A = (351 kg*m*s^-2)/53kg

A=(351/53) ms^-2

a = 6.62 ms^-2
