Block on a Block Problems
Two blocks are pushed against a wall and held at equilibrium. If all surfaces have friction, then what is the direction of friction from the wall on block B
- At t=15 s, the acceleration of 2 kg block is 11 ms−2.
- At t=1 s, the force of friction between 2 kg and 4 kg blocks is 2 N.
- At t=4 s, the force of friction between the ground and 4 kg block is 18 N.
- At t=1 s, the force of friction between 2 kg and 4 kg blocks is zero.
Two blocks m1and m2, are acted upon by the forces F1 and F2 as shown in the fig. If there is no relative sliding between the blocks and the ground is smooth, find the magnitude of static friction between the blocks.Make necessary assumptions.
