An electric motor that is 98% efficient runs off of a 100 W power supply. What is the maximum speed the motor could lift a 10 kg mass straight up? What is the maximum speed the motor could move the 10 kg mass across a frictionless surface? (This second question can only be answered in terms of the force that the motor applies to the mass. So, I should have added something like: Assume the electric motor is attached to the mass by a cable that has a maximum force tension of 3 kN.)
A spring is used to stop a 32 kg metal sphere which is moving down a 30° incline, as shown in Figure Q2(a). The spring has a constant k = 33 kN/m and initially compressed 50 mm. Given that the velocity of the metal sphere is 5.5 m/s when it is 5 m from the spring and the friction can be neglected. (Gravity g = 9.81 m/s?) Q2. (a) Determine all the kinetic and potential energy components at the initial (i) and final position of the metal sphere. (Let the x be the additional compression of the spring). (ii) Calculate the maximum additional deformation of the spring requires to bring the metal sphere to rest. (iii) Determine after the metal sphere come into rest will it rebound upwards the slope or not? if can how much it will move up again the slope until it temporary at reset otherwise stated the reason why the metal sphere would stay at rest. 5.5m/s m=32kg 5m 30 Figure Q2(a)
