Q5: Show that for a fielder standing
at the landing point/ range of a
cricket ball projectile the rate of
change of tan(Elevation Angle) with
Time is constant as he sees the ball
from beginning till end. The fielder is
standing in the plane of the
projectile. दिखाइये कि अगर एक फील्डर बॉल
प्रोजेक्टाइल के जमीन पर गिरने वाले बिंदु पर ही
खड़ा है, तो बॉल को शुरू से अंत तक देखने पर
समय के साथ tan(Elevation Angle) के
बदलने की दर एक समान रहती है. फील्डर और
प्रोजेक्टाइल एक ही तल में हैं.
