An astronaut on the Moon (g=1.62 m/s2) throws a rock from the ground level with a speed of 32.1 km/h directly upwards. Determine the time after which the rock reaches the height equal to three quarters of its maximum height on the way down.Provide your answer with the precision of two places after the decimal.
Hello. I am working on a problem with motion. The questions asks me to calculate the maximum height (h1), total time (t2), and speed of a ball right before it hits the ground. The question states that A person is throwing a ball upward into the air with an initial speed Vo = 10m/s. Assume that the instant when the ball is released, the person's hand is at a height ho = 1.5m. The speed of the ball at its peak height is zero, and the question needs to be solved in ascending part and descending part. I don't understand how to solve for the maximum height. What is the correct formula to use and why? For other questions like this, I will be able to solve them if I know the formulas for the ascending of the ball and the descent of the ball as well as the explanation. Thank you. For the sake of the question, the ball is being thrown straight up.

As a training exercise, a soccer player must run the length of the soccer field (leg 1), then turn around and run back to her starting point (leg 2) without stopping. If the length of the soccer field is L meters, and she runs the leg 1 in t 1 seconds, then turns around and runs leg 2 in t_2 seconds, find the following: (Write your answers using the symbols as they are written in the question.) a) Her average velocity during leg 1 was L/t'1 m-s 1, b) Her average velocity during leg 2 was L/t 2 m-s1. c) Her average velocity over the entire exercise was m-s 1. d) Her average speed during the entire exercise was 2L/t_1+t_2 m-s1.

Some troublemaking kids are dropping water balloons from the roof of your apartment building. You are in your ﬁfth-ﬂoor room and your window is 25 m above the sidewalk outside. You look outside and see that each balloon hits the pavement 1.5 s after passing your window. Express answers using 2 signiﬁcant ﬁgures. a) How fast are the balloons traveling when they pass your window? b) Assuming the balloons are being released from rest, from what height above your window are they being released? c) If you threw a balloon upwards from your window with an initial speed of 6.5 m/s, would you be able to get it to the roof?

Assume you are driving a car at a constant speed of 76 km/h. Suddenly you see a deer standing on the highway and you must put on the brakes. Your reaction time (time elapsed between the moment you see the deer and your foot hitting the brakes) is 0.118 s. The brakes provide an acceleration with a magnitude of 4 m/s2, and a direction opposite the initial velocity. How do you find the total distance traveled?
The acceleration of a particle is a constant. At t = 0 the velocity of the particle is (15.8î + 18.4ĵ) m/s.At = 3.6 s the velocity is 10.5ĵ m/s. (Use the following as necessary: t. Do not include units in your answers.) (b) How do the position (in m) and velocity (in m/s) vary with time? Assume the particle is initially at the origin.
