At what launch angle or angles will a projectile land at 0.2 of its maximum possible range on flat ground? please show details
Homework Answers
By R = u^2sin2?/g
=>R(max) = u^2/g [for? = 45*] -----------(i)
=>Let the angle is ? in 2nd condition:-
=>By R = u^2sin2?/g
=>0.2R(max) = u^2sin2?/g
=>0.2 x u^2/g = u^2sin2?/g
=>sin2? = 0.2
=>sin2? = sin12*
=>? = 6*

A projectile is launched up and to the right over flat, level ground. If air resistance is ignored, its maximum range occurs when the angle between its initial velocity and the ground is 45°. Which angles would result in the range being equal to half the maximum? (Enter your values from 0 to 90°.) smaller value ? larger value?

A projectile is launched from level ground at an angle of 30
degrees to the horizontal. If the magnitude of the launch velocity
is 30 m/s, calculate the time rate of change in speed and radius of
curvature when t=1, 2, and when the projectile is at its max
height.
