Answer» Step-by-step explanation: maximum height can be attained only when the PROJECTILE is LAUNCHED at 90° threrfore , H= u^2/2g 25×2×9.8= u^2 490=u^2 7√10=u then for range , the maximum range OCCURS at 45° R = u^2/g R = 490/9.8 R = 50 m

Answer»

Step-by-step explanation:

maximum height can be attained only when the PROJECTILE is LAUNCHED at 90°

threrfore ,

H= u^2/2g

25×2×9.8= u^2

490=u^2

7√10=u

then for range ,

the maximum range OCCURS at 45°

R = u^2/g

R = 490/9.8

R = 50 m
