An object is dropped in an unknown planet from a height of 50 m, it reaches the ground in 2 s. The acceleration due to gravity in this unknown planet is ______
Calculate the average velocity of the particle whose position vector changes from `vecr_1 = 5hati + 6hatj` to `vecr_2 = 2hati + 3hatj` in a time 5 second.
The following table gives the range of a particle when thrown on different planets. All the particles are thrown at the same angle with the horizontal and with the same initial speed. Arrange the planets in ascending order according to their acceleration due to gravity, (g value).
