No, nobody can swing upwards at 60 degrees, as the shoulder's are the pivot point, and your upper body would need to lean back farther than it's capable of.
Fastest part of your swingspeed at the rackethead should be at ball contact, slighly in front of your body.
If you aimed 60 degrees upwards, the fastest rackethead speed would be achieved behind you, 1 foot behind the baseline.
