An astronaut on a strange new planet having no atmosphere finds that she can jump up to a maximum height of 27 m when her initial upward speed is 6.0 m/s. what is the magnitude of the acceleration due to gravity on the planet?

Explanation:

Given that,

Initial upward speed, u = 6 m/s

Maximum height of the astronaut, h = 27 m

Let g is the acceleration due to gravity on the planet. It can be calculated using the conservation of energy as :

So, the magnitude of the acceleration due to gravity on the planet is . Hence, this is the required solution.  

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6
