Guys i need some help with my homework...having difficulty with these three questions: any help will be appreciated..
thanks
1. The vertical component of the acceleration of a sailplane is zero when the air pushes up against its wings with a force of3.1kN.
(a) Assuming that the only forces on the sailplane are that due to gravity and that due to the air pushing against its wings, what is the gravitational force on the Earth due to the sailplane? kN upward
(b) If the wing stalls and the upward force decreases to 2.2 kN, what is the acceleration of the sailplane? m/s2 downward
2. During a balloon ascension, wearing an oxygen mask, you measure the weight of a calibrated 4.50-kg mass and find that the value of the gravitational field strength at your location is9.790 N/kg. How high above sea level, where the gravitational field strength was measured to be 9.803 N/kg, are you located?
3.A model sailboat is slowly sailing west across a pond at0.18m/s. A gust of wind blowing at 28° south of west gives the sailboat a constant acceleration of magnitude0.22m/s2during a time interval of2.2s.
(a) If the net force on the sailboat during the 2.2-s interval has magnitude 0.375 N, what is the sailboat's mass? kg
(b) What is the new velocity of the boat after the 2.2-s gust of wind?
