Question

Obtain expression for the time of flight of a projectile. State right hand screw rule.

Answer 1

Answer:

Time of Flight

The time of flight of a projectile motion is the time from when the object is projected to the time it reaches the surface. As we discussed previously,

T

depends on the initial velocity magnitude and the angle of the projectile:

T=2⋅uy/g

T=2⋅u⋅sinθ/g

we keep our right hand parallel to the first vector of the cross-product (eg: A in A cross B). Such that the tip of the fingers point in the direction of the vector, annd fold our hand in a fist moving towards the second vector (B vector) then the direction of the thumb gives the direction of the resultant.
