Adaredevil is shot out of a cannon at 51.7 ◦ to the horizontal with an initial speed of 31.9 m/s. a net is positioned a horizontal distance of 39.1 m from the cannon. at what height above the cannon should the net be placed in order to catch the daredevil? the acceleration of gravity is 9.8 m/s 2 . answer in units of m.

30.34 m

Explanation:

Given

launch angle

Initial velocity u=31.9 m/s

Position of net = 39.1 m

We know equation of trajectory of a projectile is

Therefore Net should be placed 30.34 m above ground

sleep paralysis is a parasomnia, events associated with sleep.
