how can you measure the acceleration of an automobile using instruments located only within the automobile?

A man is runing 2000 CM in 30 seconds.find how much KM he run in 30 seconds?

A bird generates a lift of 3 x 10^1 N at its maximum velocity of 14m/s, the bird has a mass of .020kg what is the tightest radius that it can turn and maintain its altitude?

You are on a circular racetrack that does not have banked turns. The radius of the tracks circle is 2.5 x 10^2m. Starting from rest you accelerate uniformly at a rate of 4m/s^2. The coefficient of friction is .8, how many seconds will it take to start sliding off of the track?

Tarzan swings from a vine that is 15m long and has a tensile strength of 1 x 10^2 m. He grabbed it while running at 7m/s and he weighs 80kg. Will the vine break when he swings on it?

A centrifuge is used and runs at 3600 rpm. When it is shut off it comes to a stop. If it completed 30 revolutions in the time from the maximum speed to when it stopped, what was the angular accelerations assuming it was constant?

You are driving at 40mph which for your tire size equates to 50 rad/s. You accelerate uniformly to a speed of 48mph in 5 seconds. How many revolutions did your tire make?

A mustang going from 0 to 60 in 3.5 seconds has an acceleration of 7.7m/s. Radius of the tires is .35m, what is the angular displacement of the tires between the rest time and 60mph. Provide answer in radians and use the revolution of a tire is 2 x pie x r to convert to the linear distance that was traveled. Then also confirm this by using kinematics.

What will be the distance moved by a freely falling body in nth second of its motion?(initial velocity=0)

the mean free path of a molecule of He gas is α. Its mean free path along any arbitrary coordinate axis will be
