Hi, was wondering how you could find the inverse of

x(t)= ( 2t / (1+t^2) , (t^2-1) / (1+t^2) ) and what is it.

Cheers

A meteor just crashed in Peru, making the village sick. What if we find microscopic life on Mars, bring it back to Earth, and it is devastating to human life? What are the odds of this?

a gyroscope consists of a metal disc of moment of inertia
I = 4.5 x 10^-5 kg m^2, mounted on a light axle of radius 2 mm
which rotates freely within a frame

I set the gyroscope in motion by pulling a 30 cm length of string, which I wound around the axle. I now apply a force of
10 N (in a direction perpendicular to the axle) to the string as it unwinds. Friction / air resistance negligible.

1. Calculate final angular speed & magnitude of angular momentum of the gyroscope

2. How long would it take me to pull out the 30 cm of string.

I calculated the work done ( 3 Nm) and torque (0.02 Nm)

Let the elevator have a mass of 1700 kg and an upward acceleration of 2.5 m/s2. Find T.

If the formula is T=ma then multiplying 1700 with 2.5 should give me the value for T but for some reason I'm not getting the right answer. Is it supposed to be 4250 or am I missing something? Thanks!
