A 250-n force is directed horizontally as shown to push a 29-kg box up an inclined plane at a constant speed. Determine the magn
itude of the normal force
1 answer:
Answer:
246.38N
Explanation:
Check the complete question in the attached diagram
The normal force acting on the body on an inclined is equal to the weight of the object as shown;
Weight = Normal force = mgcosθ
m is the mass of the box = 29kg
g is the acceleration due to gravity = 9.81m/s²
θ is the angle of inclination = 30°
N = 29 * 9.81 * cos 30°
N = 284.49cos30°
N = 246.38N
<em></em>
<em>Hence the magnitude of the normal force is 246.38N</em>

V = 156.13 [cm³]
Explanation:
El volumen de un solido con forma de paralepipedo se puede calcular por medio de la siguiente formula:
donde:
V = volumen [cm³]
ancho = 3.4 [cm]
largo = 11.2 [cm]
alto = 4.1 [cm]
