Two blocks, stacked one on top of the other, slide on a frictionless horizontal surface. The surface between the two blocks is r

devlian [24]

Answer:

$F_{net} = 31.88 N$

Explanation:

When top block is just or about to slide on the lower block then we can say that the frictional force on it will be maximum static friction

So we will have

$F_{net} = ma$

$F_s = ma$

$\mu_s mg = ma$

$a = \mu_s g$

$a = (0.50)(9.81)$

$a = 4.905 m/s^2$

now for the Net force on two blocks to move together

$F_{net} = (m_1 + m_2) a$

$F_{net} = (2.3 + 4.2)(4.905)$

$F_{net} = 31.88 N$

Gravity can be described as (2 points)

ladessa [460]

Answer:

"the force of attraction between two objects"

Explanation:

According to Newton's Universal Law of Gravitation, gravity is a force of attraction acting between objects that possess mass. The fact that we only observe gravitational attraction (as opposed to repulsion) makes gravity unique among the known forces.
