- 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, 92.3 m above the ground, and the stone hits the ground 6.18 s later. What is the value of g on Planet #1? 1 14.94 m/s^2 2 29.87 m/s^2 3 4.83 m/s^2 4 2.42 m/s^2A swimmer bounces straight up from a diving board and falls feet first into a pool. She starts with a velocity of 4.0 m/s, and her takeoff point is 1.1 m above the pool. Which of these two valid methods is the easiest to find how long her feet are in the air? Group of answer choices Break the problem in two parts. For part 1, find the time to reach her highest point by using v0 = 4 m/s, a = -9.8 m/s2, and vf = 0 m/s. For part 2, you can use the highest point above the board found in the previous problem and add it to her height above the pool. Then, using v0 = 0 m/s and a = -9.8 m/s2, you can find the time to reach the ground. Since you only care about the end points in this case, you can use v0 = 4 m/s, a = -9.8 m/s2, and Δy = -1.1 m to find the time to reach the ground.A ball is tossed upward from the top of a tower, located 50 m above the ground.If the ball has an initial velocity of 15 m/s, how long will it take to hit the ground?Assume a(t)= -10 m/s2 a= acceleration t=time

What is the velocity of the object at t = 19.10 s? m/sA ball is thrown straight upward from ground level with a speed of 22 m/s How much time passes before the ball strikes the ground if we disregard air resistance? 2.2 s 1.4 s 4.5 s 0.7 sFrom a height of 11.0 m an object is sent directly downward with an initial velocity of 1.2 m/s. Determine how long the object stays in the air before touching the ground below. 1.38 s 1.20 s 1.86 s ○ 1.00 s

- Starting at x = - 14 m at time t = 0 s, an object takes 17 s to travel 42 m in the +x direction at a constant velocity. On a sheet of paper, make a position vs. time graph of the object's motion. What is its velocityThe 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, 63.8 m above the ground, and the stone hits the ground 3.88 s later.
