A human expedition lands on an alien planet. One of the explorers is able to jump a maximum distance of 14.0 m with an initial speed of 2.20 m/s. Find the gravitational acceleration on the surface of the alien planet. Assume the planet has a negligible atmosphere. (Enter the magnitude in m/s2.) 0.17285714x Note that the given distance is the maximum horizontal range, not the maximum vertical height, for the given initial speed. m/s2 My Notes Ask Your Teache

Explanation / Answer

here,

a)

velocity vector , v = 4.69 * ( cos(40) i + sin(40) j)

v = 3.6 i m + 3.01 j m

b)

the position vector , s = 26.7 * ( cos(95) i + sin(95) j )

s = - 2.32 i m + 26.6 j m

----------------------------------------------------

maximum distance , R = 14 m

initial speed , u = 2.2 m/s

let the accelraion due to gravity be a

for maximum range

R = u^2 /a

14 = 2.2^2 /a

a = 0.35 m/s^2

the accelraion due to gravity is 0.35 m/s^2
