Physics An object is thrown upward at an acute angle ?? with respect to the horizontal. The object leaves the thrower’s hand at a speed of 64 feet per second. Its horizontal coordinate x is given by x = (64 cos ??)t, where x is in feet and t is the time (in seconds) since the object was thrown. If when and the expression for x can be written as x = (64 sin(?? - c))^t for some c that  find the values of ?? and c (in degrees).
