IKAROS is a spacecraft designed to test the possibility of using solar sails as space propulsion. The spacecraft has a mass of 290 kg. The force on the sails was measured to be 1.12 mN (m = milli).
A. Draw a free body diagram of the experiment.
B. What is the weight of IKAROS on Earth?
C. What is the acceleration of IKAROS?
D. Assuming IKAROS started at rest, how fast would it be going after 24 hours?
E. How fast would IKAROS be going after 4 months (assume 30 days/month)?

Problem Solving: LightSail 2 BOOM LENGTH TOTAL SAIL AREA SIZE REFERENCE 5.6 x 5.6 m (18.4x 18.4ft) 4 m (13ft) 32 m (344ft) Boxing Ring SAIL DEPLOYMENT PROPULSION LightSail 2 was a satellite that was designed to use solar radiation to change its altitude as it circled Earth. The spacecraft had a mass of 5.0kg. It was originally launched by a rocket with its sail closed, and established an orbit at an altitude of 720 km above Earth's surface. Then...
Vibrational Motion Introduction If an object is following Hooke’s Law, then Fnet = -kx = ma Since acceleration is the second derivative of position with respect to time, the relationship can be written as the differential equation: kx = m δ2xδt2/{"version":"1.1","math":"<math xmlns="http://www.w3.org/1998/Math/MathML"><mi>k</mi><mi>x</mi><mo> </mo><mo>=</mo><mo> </mo><mi>m</mi><mo> </mo><mfrac bevelled="true"><mrow><msup><mi>δ</mi><mn>2</mn></msup><mi>x</mi></mrow><mrow><mi>δ</mi><msup><mi>t</mi><mn>2</mn></msup></mrow></mfrac></math>"} Methods for solving differential equations are beyond the scope of this course; in fact, a class in differential equations is usually a requirement for a degree in engineering or physics.
