Explanation:

The normal component of force applied = 5.23 sin 51 N

Let  R be the reaction force from the ground . Weight of the toy

W = mg

.518 x 9.8

= 5.07 N

As there is no movement in vertical direction , these forces will um up to zero

W - R - 5.23 SIN 51 = 0

R = W  - 5.23 SIN 51

5.07 - 4.06 N .

1.01 N .
