Cesar Shaw · Answer 1

Horizontal velocity is 12.5m/s

Magnitude of actual velocity we find like this:

cos25*Vm=12,5

Vm = 12,5/cos25

Vm = 13.8m/s

vertical velocity is:

Vv = Vm*sin25 = 5.83m/s

Time after ball will stop ascending is:

t=Vv/a = 5,83/9.81 = 0.59s

Finally we calculate traveled distance:

S=t*Vh = 0.59*12,5 = 7.42m
