Hello i would like to know if there is a course or a book in which to learn quantum mechanics is easier, i am currently studying quantum mechanics, but it is a little complicated because i have some mathematical doubts, but nevertheless i would like to know if there is a course or book that explains and develops the problems so that they are understandable. and if there is no book or course i would appreciate an honest and complete answer, you very much and greetings.
sorry i know that this is not a problem but what better to ask the experts do not believe.

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
