i,is time of flight increase or decrease?why?
ii,hmax >> >> >>
iii,the range >> >> >>
iv,the striking angle >> >> >>

So I want to find the speed an object hits the ground. I have the initial speed 45ms, the angle 50degrees and its time in flight 6.7s. So the final speed before impact should be: (45ms)sin(50)9.81(6.7)=31.25...ms Does this seem correct. …
