2 blocks of masses 1.0 kg and 2.0 kg are pushed by a constant applied force F across a horizontal frictionless table with a constant acc such that the blocks remain in contact w each other. the 1.0 kg block pushes the 2.0 kg block with a force of 2.0 N. acceleration of the two blocks?

In a vernier instrument the main scale is in 1/2 mm divisions .vernier is made by redividing 19 such divisions into 20 equal parts. calculate the least count of the instrument.

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping
