how did u wrote ??
e=vtan@sin@/vcos@
a metal ball falls vertically nd strikes plane inclined at an angle (theta) to d horizontal (theta <45). d ball rebounds horizontally. show dat d fraction (1-e) of d kinetic energy is lost during d impact if m is d mass nd u is d speed of d ball before impact nd coeff. of restitution is e????
