POSSIBLE POINTS: 7.32 Julietta and Jackson are playing miniature golf. Julietta's ball rolls into a long, straight downward incline with a speed of 2.95 m/s and accelerates at 3.76 m/s/s for 2.74 seconds until it reaches the bottom of the incline and then continues along an elevated section. Determine the length of the incline. BIUT T, 0/ 10000 Word Limit 2 3 4 5 67 8. 10 Nex Sign dut

A golf ball is dropped from rest from a height of 9.90 m. It hits the pavement, then bounces back up, rising just 6.30 m before falling back down again. A boy then catches the ball when it is 1.40 m above the pavement. Ignoring air resistance, calculate the total amount of time that the ball is in the air, from drop to catch. Number i Units

The next few questions challenge you to figure out the acceleration due to gravity ( g ) on various hypothetical alien planets. On Planet #1, you drop a stone from rest, 76.1 m above the ground, and the stone hits the ground 6.17 s later. What is the value of g on Planet #1?     24.67 m/s^2     4.00 m/s^2     2.00 m/s^2     12.33 m/s^2
