A child drags a 0.518 kg toy elephant

across flat ground at constant speed,
with a 5.23 N force at a 51.0° angle.
What is the normal force acting on
the toy?

Answer:

Step-by-step 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 .
