1.)
a.) The velocity of a diver just before hitting the water is -7
m/s, where the minus sign indicates that her motion is directly
downward. What is her displacement during the last 1.03 s of the
dive?
______m
b.) 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 +12 m/s and measures a time of 18.0 s before the rock returns to his hand. What is the acceleration (magnitude and direction) due to gravity on this planet? (Indicate direction by the sign of the acceleration.)

The velocity of a diver just before hitting the water is -10.2 m/s, where the minus sign indicates that her motion is directly downward. What is her displacement during the last 1.07 s of the dive?
The velocity of a diver just before hitting the water is -11.9 m/s, where the minus sign indicates that her motion is directly downward. What is her displacement during the last 1.34 s of the dive?
The velocity of a diver just before hitting the water is -11.7 m/s, where the minus sign indicates that her motion is directly downward. What is her displacement during the last 1.16 s of the dive? All steps please!
Consult Multiple-Concept Example 5 in preparation for this problem. The velocity of a diver just before hitting the water is -11.9 m/s, where the minus sign indicates that her motion is directly downward. What is her displacement during the last 1.23 s of the dive?
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 +18.9 m/s and measures a time of 16.1 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)
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 +17.9 m/s and measures a time of 22.0 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)
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 +15 m/s and measures a time of 20.0 s before the rock returns to his hand. What is the acceleration (magnitude and direction) due to gravity on this planet? See Diagram below: Show your work below:
Concept Simulation 2.3 offers a useful review of the concepts central to this problem. 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 +15.0 m/s and measures a time of 15.1 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 +/-5%
The graph shows the kinematics (vertical position, velocity, and acceleration) of the center of gravity of a diver and the reaction force of the diving boar during the takeoff phase for a 3 1?2 backward somersault dive in the tuck position. a) At what time(s) (approximately) does the displacement of the diver change direction? How many times does this occur during the takeoff phase of the dive? b) When does the center of gravity accelerate in the upward direction and...
Suppose you are an astronaut and you have been stationed on a distant planet. You would like to find the acceleration due to the gravitational force on this planet so you devise an experiment. You throw a rock up in the air with an initial velocity of 9 m/s and use a stopwatch to record the time it takes to hit the ground. If it takes 5.2 s for the rock to return to the same location from which it...
