A force of 100 newtons is applied to a box at an angle of 36° with the horizontal. If the mass of the box is 25 kilograms, what is the horizontal
acceleration of the box?
OA
1.52 meters/second²
OB. 3.24 meters/second²
OC. 5.48 meters/second²
O D.
6.87 meters/second²
OE
7.15 meters/second²

Respuesta :

Answer:

See below

Explanation:

I will assume the force is in a DOWNWARD direction ( I believe it makes no answer difference)

Horizontal component is then 100 cos 36° =80.9 N

F = ma

80.9 = 25 kg  *a

a = 3.24 m/s^2
