An astronaut on a distant planet wants to determine its acceleration due to gravity. The astronaut throws a rock straight up with a velocity of +10.4 m/s and measures a time of 22.9 s before the rock returns to his hand. What is the acceleration (magnitude and direction) due to gravity on this planet? (positive - up, negative down) Number Units the tolerance is +/-2% K TO TEXT Question Attempts: Unlimited SAVE FOR LATER SUBKET ANSWER

Explanation / Answer

Given that

speed of the rock u=10.4 m/s

time t=22.9 sec

now we find the acceleration due to gravity of the planet

acceleration due to the gravity g=v/t=10.4/22.9=0.45 m/s^2

the object moves upwards
