An astronaut on a strange planet finds that he can jump a maximum horizontal distance of 30m if the initial speed is 9 m/s/ (a) what is the accelration of gravity on the planet? (b) what is the maximum height to which he can jump if he starts with thesame initial speed?

Answer

(a) 2.7m/s^(2)`, (b) 15m

Explanation

`R_("max")=(u^(2))/(g)`
`H_("max")=(u^(2))/(2g)`
