Projectile motion equations time of flight free#

Calculate the (I) time of flight of the stone (g= 10m/s) (Wassce 2004)Ħ. A stone, thrown horizontally from the top of a vertical wall with a Velocity of 15m/s, hits the horizontal ground at a point 45m from the base of the wall. Horizontal distance is given by X= utcos O= 10×3cos O= 30×1= 30m.ĥ. Calculate the horizontal distance covered by the particle before hitting the ground. A particle is projected horizontally at 10m/s from a height of 45m. With the aid of a sketch, explain how h varies with: (a) t (b)t 2.(Wassce 2009) A particle is dropped from a vertical height h and falls freely for a time t.

With the aid of a diagram, show that the time of flight is equal to 2usin O/g, where g is the acceleration of free fall.( Wassce 2013)ģ. A projectile is released with a speed u at an angle O to the horizontal. Calculate the horizontal distance travelled by the particle when it hits the level ground.

Note that it is advisable to work from first principles with equations y=utsin O -½ gt 2ġ.A particle is projected horizontally at 10m/s from the top of a tower 20m high. Maximum height (H) is defined as the highest vertical distance reached as measured from the horizontal projection plane. The range (R) is defined as the horizontal distance from the point of projection to the point where the projectile hits the projection plane again. Time of flight (T) can be defined as the time required for it to return to the same level from which it was projected. Examples can be located in sports and warfare. A projectile is an object thrown into the air or launched into space and moves freely by itself under the influence of gravity and air resistance.
