Question
Starting from rest, A flat car is given a constant acceleration ao = 2 m/s2. A cable is connected to a crate A of mass 50 kg as shown. Neglect the friction between floor and car wheels and mass of pulley. The coefficient of friction between crate & floor of the car is m = 0.3. The tension in cable is -
Options
A.700 N
B.350 N
C.175 N
D.0
Solution
If acceleration of the car is a0, acceleration of the block 2a0 = 2 × 2 = 4 m/s2 (→)
F = μN = 0.3 × 50 × 10 = 150
T − F = ma
⇒ T − 150 = 50 × 4
⇒ T = 350 N.
