A block of mass 2 kg rests on a rough horizontal plank , the coefficient of friction between the plank and block is 0.3. If the plank is pulled horizontally with a constant acceleration of 4 m//s^(2) , the distance moved by the block on the plank in 5secondstarting from rest (in m) is : (Take g = 10 m//s^(2))

1.	A block of mass 2 kg rests on a rough horizontal plank , the coefficient of friction between the plank and block is 0.3. If the plank is pulled horizontally with a constant acceleration of 4 m//s^(2) , the distance moved by the block on the plank in 5secondstarting from rest (in m) is : (Take g = 10 m//s^(2))
Answer» 5 10 25 50 Solution :`s = (1)/(2) at^(2)`
