## Homework Statement

A person starts to mow a lawn with 50kg old fashioned push lawn mower. The handle of the mower makes an angle of 45 degrees with the sure of the lawn. A 200 N force is applied along the handle of the mower by the person

a. Determine the normal force exerted by the ground on the mower

b. If u=0.2, determine if the mower moves with a constant speed.

c.How far the mower will travel if the person pushes it for 1min along the staright line?

## Homework Equations

## The Attempt at a Solution

a) Fnormal = 200Nsin45 = 141

b) F=uFnormal (.2)(141) = 28.2

141-28.2

=112.8

F = ma

112 / 50

a = 2.24

c. ?

Not sure if a or b are correct
