Find the maximum distance d that the glider moves to the right if the air is turned off, so that there is kinetic friction with coefficient 0.320. Express your answer with the appropriate units.

answer : d ( 10 d + 62.784 ) = 0.1125

Explanation:

Calculate the maximum distance D

Kinetic friction = 0.320

= 1/2 * k * d^2 + 0.320 *m *g * d = 1/2 * m * v^2

= 1/2 * 20 * d^2 + ( 0.320 * 20 * 9.81 ) d = 0.1125

= 10 d^2 + 62.784d = 0.1125

d ( 10 d + 62.784 ) = 0.1125

1) estimating temperature to the nearest tenth of a degree

2) estimating the mass of the sample to the nearest tenth of a gram

4) the position of the cups of sand and water under the heat lamp
