FrictionHard
Question
A block of mass M = 5 kg is resting on a rough horizontal surface for which the coefficient of friction is 0.2. When a force F = 40 N is applied as shown in figure the acceleration of the block will be (g = 10 m/s2) :
Options
A.5.73 m/sec2
B.8.0 m/sec2
C.3.17 m/sec2
D.10.0 m/sec2
Solution
N = 50 − 40 sin 30 = 30
a =
= 5.73 m/sec2Create a free account to view solution
