One of the explorers is able to jump a maximum distance of 15.0 m with an initial speed of 3.50 m/s. Find the gravitational acceleration on the surface of the alien moon. Assume the planet has a negligible atmosphere. (Enter the magnitude in m/s.) X Note that the given distance is the maximum horizontal range, not the maximum vertical height, for the given initial speed. m/=2 Need Help? Read It Submit Answer 8.

The height of the counter is 1.38 m. The mug slides off the counter and strikes the floor 1.00 m from the base of the counter. (a) With what velocity did the mug leave the counter? X Does the time required for the mug to hit the floor depend on its initial horizontal velocity? m/s (b) What was the direction of the mug's velocity just before it hit the floor? (below the horizontal) Need Help? Read it Master It Submit Answer 9. [5/10 Points] DETAILS PREVIOUS ANSWERS SERPSE10 4.3.OP.013.MI. MY NOTES PRACTICE ANOTHER A placekicker must kick a football from a point 36.0 m (about 40 yards) from the goal. Half the crowd hopes the ball will clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 23.6 m/s at an angle of 49.09 to the horizontal. (a) By how much does the ball clear or fall short of clearing the crossbar? (Enter a negative answer if it falls short.) 10.135 X It may be helpful to first determine the time required for the ball to reach the goal. m (b) Does the ball approach the crossbar while still rising or while falling? O rising falling
