Bones break roughly and an acceleration of 206 m/s^2. That is, if you fall and decelerate from your fall at rate greater than 206 m/s^2 your bones can break. If you're a motorcycle racer and get thrown vertically in the air 2.9 m, how thick (cm) should your protective padding be such that you are not likely to break any bones. Only consider the vertical motion, since most racers slide when they hit the ground. (cm)

A ball is thrown from the ground with an initial velocity of 20 m/s at an angle of 30 degrees above the horizontal. Ignoring air resistance, calculate the maximum height reached by the ball and the horizontal distance it travels before hitting the ground. Assume the acceleration due to gravity, g, is 9.8 m/s² and take the direction of upward motion as positive.

Falcons are excellent fliers that can reach very high speeds by diving nearly straight down. To pull out of such a dive, a falcon extends its wings and flies through a circular arc that redirects its motion. The forces on the falcon that control its motion are its weight and an upward lift force—like an airplane—due to the air flowing over its wings. At the bottom of the arc, as shown, a falcon can easily achieve an acceleration of 15 m/s2. A falcon starts from rest, does a free-fall dive from a height of 30 m, and then pulls out by flying in a circular arc of radius 50 m. Which segment of the motion has a higher acceleration?A. The free-fall diveB. The circular arcC. The two accelerations are equal.

A particle has a velocity of v= (3i+5j)m/s and a constant acceleration of a=(-1.5i-4.5j)m/s^2 What is its velocity after 2 seconds? Is it moving faster or slower after 2 seconds?

If the height of the water slide is h = 3.8m, and the person's initial speed at the top is 0.70m/s , what is the horizontal distance between the base of the slide and the splashdown point of the person?

Problem 2: An object is thrown off the top of a 38-m tall building with a velocity of 350 m/s at an angle of 8.2° with respect to the horizontal. Part (a) How long is the object in the air in seconds? Numeric : A numeric value is expected and not an expression. t = Part (b) What is the maximum height the object reaches above the ground in meters? Numeric : A numeric value is expected and not an expression. hmax = Part (c) What is the horizontal distance the object covers in meters? Numeric : A numeric value is expected and not an expression. Ax =.

On the planet Koozebane, if a pebble is dropped from height h, it falls to the surface in time t. Data for the acceleration = 4.100 [m/s^2]; the height = 4.900 [m]. What is the time? Submit Answer Tries 0/12

The leaning tower of Pisa is 57 m tall. Supposedly Galileo investigated the behavior of falling objects by dropping them from the top of this tower and timing their descent. How long would it take an object to fall 57 m if air effects are negligible? Express your answer in 2 decimal places and in seconds.

Please answer the following, thank you!

A ball is thrown eastward into the air from the origin (in the direction of the positive x-axis). The initial velocity is 40 i +64 k, with speed measured in feet per second. The spin of the ball results in a southward acceleration of 4 ft/s2, so the acceleration vector is a = -4 j - 32 k. Where does the ball land? (Round your answers to one decimal place.) X ft from the origin at an angle of 5.7 X from the eastern direction toward the south. 80.4 With what speed does the ball hit the ground?
