A garbage can of mass 12 kg standing on horizontal ground is pushed by a horizontal force of 40N. If the coefficient of static friction is 0.32 and the coefficient of dynamic or kinetic friction is 0.24 between the can and ground, the acceleration of the garbage can is
m/s2

not too sure thinking all accelerations are pointed down

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
