  • max height attained =v2sin2​​​angle /2g                                                                                                                                                     =   100×100×sin260 /2×10     =10000×3 /4 ×20    =375m                                                                                Time of flight =2vsinangle /g                                                                                                                                             = 2×100 ×sin 60 /10        =17.3 second
