Name: ....... Quiz 3 due by 03/04/2023 1- (20 Pts) True or False: a. (T or F) It is the natural tendency of all objects to eventually come to a rest position. b. (T or F) Speed is a scalarquantity which is the magnitude of the instantaneous velocity at any time, t. C. (T or F) Swimming is possible on account of the third law of Newton. . (T or F) If a particle has a constantvelocity, it must have a constantspeed. 2- (10 Pts) A 30 kg child exerts a force of 100 N on a 50 kg object. The force the object exerts on the child is? a.
