A92 kg astronaut is holding a 18 kg microsatellite while drifting away from a space station at a speed of 2.7 m/s. the astronaut pushes the satellite way from her in the direction that she is drifting. the relative velocity between the satellite and her is 2.4 m/s after she pushes it way. what is her velocity relative to the space station after she pushes the satellite away?

Distance covered, s = 8ft - 4ft = 4 ftinitial velocity, u = 34 ft/sthe acrobat is moving upwards and therefore, a = -g = -9.81 m/s^2 = 32.19 ft/s^2applying equation of motion; s = ut -1/2gt^2then,4 = 34t -1/2*32.19t^24 = 34t - 16.095t^2rearranging; -16.095t^2 + 34t - 4 = 0solving the quadratic equation; t = {-34 +/- sqrt [34^2 - 4(-16.)]}/2(-16.095) = 1.06 +/- 0.93 = 0.13 or 1.99the acrobat will take 0.13 seconds to be at 8 ft above the ground. additionally, once at the maximum height, the acrobat will move down and be at the same spot (that is height) after 1.99 seconds moving down.

The scientist was trying to demonstrate that humans can introduce their own biases into an experiment. bias is a prejudice in favor of one thing compared with the another.in this case, the bias is believing that mice with higher intelligence would solve the maze better.  bias in science should be avoided as it is not desirable that research becomes influenced by scientists personal beliefs.
