What is Physics Problems on Motion and Forces about?
1) Two blocks of masses m and 2m are in contact on a frictionless table. A force F is applied to 2m in one case and m in the other case. The force of contact between the blocks will be 1:2. 2) A rocket with a lift-off mass of 20,000 kg is blasted upwards with an initial acceleration of 5.0 m/s2. The initial thrust (force) of the blast is 4 x 10^5 N. 3) A body weighs 8 g when placed in one pan and 18 g when placed on the other pan of a false balance. The true weight of the body is 15.5 g.
