A block of mass 10 kg is placed on a rough horizontal surface having coefficient of friction μ = 0.5. If a horizontal force of 100 N is acting on it, then acceleration of the block will be
A
0.5 m/s2
B
5 m/s2
C
10 m/s2
D
15 m/s2
Answer
5 m/s2
Explanation
Solution
a=massApplied force – kineticfriction
=10100−0.5×10×10
= 5m/s2.
