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 TeacheExplanation / 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
