a 4 kg block is pulled with 5.6 n of force to the right. the block experiences 1.1 n of friction. what is the acceleration of the block?

The acceleration of the box is 1.125 m/s² towards right.

Explanation:

Mass of the box, kg

Force acting towards right, N

Frictional force acting towards left, N

Let the acceleration be m/s².

Now, net force acting on the box towards right is given as:

From Newton's second law of motion,

Therefore, the acceleration of the box is 1.125 m/s² towards right.

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.

explanation:

0 = 0.40 / 0 = 0

= 0.20 = 9.80 ⁄2 =?

=0 , = = 0.20 =0.50 0 0.40 ⁄

=0−122 =0−12(9.80 ⁄2)(0.50)2 =1.2
