On a planet, the acceleration due to gravity is only 7.2 m/s². A person living on that planet throws a football at 10 m/s at an angle of 48 degrees to the horizontal. The person is standing, so the ball launches from an initial height of 1.8 meters above the ground. (Ignore any air resistance here.)

What maximum height from the ground would the ball reach?
What would be the flight time before the ball gets back to the ground?

Solutions

Expert Solution

From the data given,

Acceleration due to gravity on the planet

g= 7.2 m/s^2

Initial velocity with which ball is projected is u

u = 10 m/s

Angle =48°

a) maximum height from the ground H= 5.6 m

b) time of flight t= 2.11 sec

2.) For this problem the heights are low enough that the acceleration due to gravity can be approximated as -g. (Note: even at low Earth orbit, such as the location of the International Space Station, the acceleration due to gravity is not much smaller then g. The apparent weightlessness is due to the space station and its occupants being in free-fall.) A rocket is launched vertically from a launchpad on the surface of the Earth.
