a low velocity mortar round is fired upward at an angle of 50° from the horizontal with a launch velocity of 40 m/s
What is the question.?
Do they want to know the range?
R = (Vo^2/g)*sin(2A)
2A = 100 degrees
how long before it hits the ground!
Time of flight:
T = 2*Vo sinA/g
A = 50 degrees
It spends Vo sinA/g going up and an equal amount of time coming back down
