A box of m1=74.8kg is on frictionless horizontal surface. The mass is pulled to left by rope which exerts a F of T1. A box of m2=48.5kg sits on top of m1. Its pulled by F T2=79.3N that makes an angle of 24.2° with the horizontal. the coefficient of static friction of the two masses is μ=0.554. Given that the blocks are in equilibrium, What is T1?

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.
