Ballistic curve

The soldier fired the ballistic grenade at a 45° angle. The first half ascended, and the second fell. How far and height it reached if his average speed was 1200 km/h, and 12 seconds took from the shot to impact.

Correct answer:

x =  0 km
h =  0 m

Step-by-step explanation:

v=1200km/h=333.33333 m/s vx=vcos45=235.7 m/s vy=vsin45=235.7 m/s x(t)=vxt y(t)=vtsin4521gt2  y(t)=0 vtsin45=21gt2 t=g2vsin45=48.0535s  x=vxt=235.748.0535=0 km
