XI Physics | Solved Numericals| Chapter No.4 |Rotational and Circular Motion | Part 1- #TP11 44
Class: XI, 11, First Year Unit :04 Rotational and Circular Motion Numeicals Covered: 1. A car mechanic applies a force of 800 N to a wrench for the purpose of loosening a bolt. He applies the force which is perpendicular to the arm of the wrench. The distance from the bolt to the mechanic's hand is 0.40 in. Find out the magnitude of the torque applied? (320 N m) 2. A car accelerates uniformly from rest and reaches a speed of 22 m/s in 9 s If the diameter of a tire is 58 cm, find (a) the number of revolutions the tire makes during this motion, assuming no slipping, and (b) the final rotational speed of the tire in revolutions per second. (55 rev, 12 rad /s) 3. An ordinary workshop grindstone has a radius of 7.5 cm and rotates 6500 rev/min. (a) Calculate the magnitude of centripetal acceleration at its edge in m/s2 and convert it into multiples of g. (b) What is the linear speed of a point on its edge? (3.47x104m/s2, 3.55x103g, 51 m/s) 4. A satellite is orbiting the Earth with an orbital velocity of 3200 m/s. What is the orbital radius? (3.897 x 107m) 5. A satellite wishes to orbit the earth at a height of 100 km (approximately 60 miles) above the surface of the earth. Determine the speed, acceleration and orbital period of the satellite. (Given: M= 5.98 x 1024 kg, R = 6.37 x 106 m) -------------------------- Unit 1 Measurements Q.1 to Q.9 • XI Physics | Solved Numericals| Chapter No...
