1. In the system shown in figure, all surfaces are smooth. Rod is moved by external agent with acceleration 0.9 ms vertically downwards. Force exerted on the rod by the wedge will be Newtons. 0.9m/s 2 1 kg 37 2. 3. A grass hopper can jump maximum distance 1.6 m. It spends negligible time on ground. How far can it go in 22s (in meters)? A block of mass 1 kg slides down a curved track which forms one quadrant of a circle of radius 1 m as shown in figure. The speed of block at the bottom of the track is v = 2 ms. The work done by the force of gravity is 10 x Joules. Find x? (Take g = 10 m/s) 1m: Im m 4. A particle moves with a velocity v = (51-3j+6k)ms under the influence of a constant force F (--)N. The instantaneous power applied to the particle is Watts. 5. Consider two spring balances hooked as shown in the figure. We pull them in opposite directions with equal force. If the reading shown by A is 5 N, reading shown by B will be N. B eeeeeeeeeeee
