A force of 8.0 N is along x direction, another force of 6.0 N is along +y direction. If both forces are acting on a point object

Darya [45]

Answer:

Resultant force, R = 10 N

Explanation:

It is given that,

Force acting along +x direction, $F_x=8\ N$

Force acting along +y direction, $F_y=6\ N$

Both the forces are acting on a point object located at the origin. Let the resultant force of the object is given by R. So,

$R=\sqrt{F_x^2+F_y^2+F_xF_y\ cos\theta}$

Here $\theta=90^{\circ}$

$R=\sqrt{F_x^2+F_y^2}$

$R=\sqrt{8^2+6^2}$

R = 10 N

So, the resultant force on the object is 10 N. Hence, this is the required solution.

if 1.5kg block is pulled across a horizontal surface that has a coefficient of kintic friction of 0.60. if a block is pulled by

inysia [295]

Answer:

3.2N

Explanation:

Given parameters:

Mass of block = 1.5kg

Coefficient of kinetic friction = 0.6

Force of pull on block = 12N

Unknown:

Net force on the block = ?

Solution:

Frictional force is a force that opposes motion:

Net force = Force of pull - Frictional force

Frictional force = umg

u is coefficient of kinetic friction

m is the mass

g is the acceleration due to gravity

Frictional force = 0.6 x 1.5 x 9.8 = 8.8N

Net force = 12N - 8.8N = 3.2N
