Two projectiles, one fired from from surface of earth with velocity `10 m//s` and other fired from the surface of another planet with initial speed `5 m//s` trace idential trajectories. The value of acceleration due to the gravity on the planet is

A particle is dropped from height h = 100 m , from surface of a planet. If in last 1/2 sec of its journey it covers 19 m. Then value of acceleration due to gravity that planet is :

A projectile is fired from the surface of the earth with a velocity of 5m *s^(-1) and angle theta with the horizontal . Another projectile fired from another planet with a velocity of 3 m*s^(-1) at the same angle follows a trajectory which is identical with the trajectory of the projectile fired from the earth. The value of the acceleration due to gravity on the planet is (in m*s^(-2) ) (given g=9.8 m*s^(-2) )

A projectile is fired from the surface of the earth with a velocity of 7 ms^-1 and angle theta with the horizontal. Another projectile fired from another planet with a velocity of 2.5 ms^-1 at the same angle follows a trajectory which is identical with the trajectory of the projectile fired from the earth. The value of the acceleration due to gravity on the planet is (in ms^-1 (given =9,8 ms^-2 )

a projectile is fired from the surface of the earth with a velocity of 5ms^(-1) and angle theta with the horizontal. Another projectile fired from another planet with a velocity of 3ms^(-1) at the same angle follows a trajectory which is identical with the trajectory of the projectile fired from the earth.The value of the acceleration due to gravity on the planet is in ms^(-2) is given (g=9.8 ms^(-2))
