An astronaut stands on the edge of a lunar crater and throws a half eaten Twinkie horizontally with a velocity of 5.00m/s the floor of the crater is 100.0 below the astronaut. what horizontal distance was the twinke befor hitting the floor of the crater (the acceleration of gravity on the moon was 1/6 that of the earth so divided gravity by 6).

Assume similar data for the motion of the blood in your aorta. estimate how many beats of the heart it will take the blood to get from your heart to your brain. (assume that the distance from your heart to your brain is 30 cm)

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?
