Calculate the magnitude of acceleration of a block that has a mads of 2.0 kg and is pulled along a table by a force of 15 n. the coefficient of kinetic friction between the block and surface is 0.25

5.05 ms⁻²

Explanation:

(check the graph)

when the block is pulled with a force , force of kinetic friction (Fr) appears resisiting the motion.

Fr = μR = μ*mg   (where g- gravitational acceleration = 9.8 ms⁻²)

   = 0.25 * 2 * 9.8

   =4.9 N

According to Newton's second law of motion

we can apply F = ma to the motion assuming the block is moving right

F = ma  (a - acceleration)

15 - 4.9 = 2*a

a = 5.05 ms⁻²

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).

explanation:

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
