Question

Top view of a block on a table is shown (g = 10 $m/s^2$). Find out the acceleration of the block, when friction is present. M = 10 kg

• A. 1 m
• B. 4 - 5 m
• C. (5 - 4) m
• D. 0 m

Answer 1

The correct option is B

4 - 5 m

N = 10$\times 10=100N$

$f_{max}=0.5\times 100=50N$

$\therefore F_r>f_{max}$

$\therefore a=\frac{40\sqrt{2}-50}{10}$

=4$\sqrt{2}$ - 5 m$/s^2$
