Hi -

Pretty easy question but would like to request expert opinion before submitting please?

Many Thanks

An astronaut lands on a newly-discovered planet (without an atmosphere). As an experiment, she throws vertically upwards a pure vanadium sphere of radius 2.0 cm and density 5.5 x 103' kg 1113 with an initial speed of 3.0 in 51. The point of release is 1.2 111 above the ground. She observes the sphere to travel 4.8 111 before it starts falling to the ground. Calculate the kinetic energvr of the projectile just as it hits the ground. X2 Kinetic energyr = J
