Per NCERT Example 6.5, a student pushes a 25 kg block with 55 N against friction of 50 N. What is the acceleration of the block?
AZero
B20 m/s²
C0.2 m/s² in the forward direction (using a = F_net/m = 5 N / 25 kg)
D2 m/s²
Answer & Solution
Correct answer: C. 0.2 m/s² in the forward direction (using a = F_net/m = 5 N / 25 kg)
Per NCERT Example 6.5, net force = 55 − 50 = 5 N. Acceleration = 5/25 = 0.2 m/s².
