A particle is moving in a circle of diameter 5m. Calculate the distance covered when it competes 3 revolutions. (b) (i) Define average speed. (ii) An object travels 30m in 4s and then another 30m in 2s. What is the average speed of the object? (c) Amit is moving in his car with a velocity of 45km/h. How much distance will he cover (i) in one minute and (ii) in one second.​ STEP BY STEP PLSS

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
