A paritcle is projected with velocity `(6hati+5hatj+8hatk)ms^(-1)` from a vertical tower of height 10m. If the y-axis is vertical up find time of flight (in sec).

A ball is projected horizontally with a velocity of 5 ms^(-1) from the top of a tower of height 10 m. When it reaches the ground (g=10 ms^(-2) )

A stone is projected horizontally with a velocity 9.8 ms^(-1) from a tower of height 100m. Its velocity one second after projection is

A body is projected with a velocity of 30 ms^(-1) at an angle of 30^(@) with the vertical. Find the maximum height, time of flight and the horizontal range.

A body is projected with a velocity 30 ms^(-1) at an angle of 30^@ with the vertical. Find (i) the maximum height (ii) time of flight and (iii) the horizontal range of the projectile. Take g=10 m//s^@ .
