A projectile is fired horizontally with 30m/s from a tower of height 50m .If radius of curvature of trajectory of projectile 3 seconds after projectile is fired,is 180sqrt(k) metres,then value of k is (g=10m/s^(2)

A projectile is projected at a angle 60^(@) with horozontal with speed 10 m/s. The minimum radius of curvature of the trajectory described by the projectile is

A projectile is fired horizontally with an initial speed of 20 m/s/ its horzontal speed 3 sec later is:

A stone is thrown horizontally with a velocity of 10m//sec . Find the radius of curvature of it’s trajectory at the end of 3 s after motion began. (g=10m//s^(2))

Trajectory of particle in a projectile motion is given as: y=x-(x^(2)//80) (x and y are in meters). Take g=10m//s^(2) .

A projectile is thrown horizontally with a speed of 20ms^(-1) .If g is (10ms^(-2)) ,then the speed of the projectile after 5 second will be nearly

A body is projected horizontally from the top of a tower of height 10m with a velocity 10m/s .Its velocity after 1 second is

A projectile is fired horizontally with velocity of 98 m/s from the top of a hill 490 m high. Find (a) the time taken by the projectile to reach the ground, (b) the distance of the point where the particle hits the ground from foot of the hill and (c) the velocity with which the projectile hits the ground. (g= 9.8 m//s^2) .

A particle is thrown horizontally from the top of a tall tower with a speed of 10m/s. if radius of curvature of path followed is 4sqrt(2k m at t=1sec, then find the value of k.

Range of a projectile with time of flight 10 s and maximum height 100 m is : (g= -10 m//s ^2)
