QUESTION 2 Remember that centripetal force and centripetal acceleration is the special name we give to...
01. (i) Calculate the centripetal acceleration of the Earth in its orbit around the Sun, (ii) And the net force exerted on the Earth. iii) What exerts this force on the Earth? Assume that the Earth's orbit is a circle of radius 1.5 X 10' m (iv) Calculate the Gravitational Force between the Earth and the Sun. (v) Compare the Gravitational Force to that net force from section (ii) above. Given that F mg (vi) Calculate the acceleration due to...
QUESTION 5 A centripetal force of 150 N acts on an 800 kg satellite moving with a speed of 4,500 m/s in a circular orbit around a planet. What is the acceleration of the satellite in m/s2? 0.19 m/s2 0.24 m/s2 0.30 m/s2 0.21 m/s2 QUESTION 6 An airplane has a mass of 4,800 pounds. If a force of 130,000 N is applied, what is the acceleration is g's? 5.8 g 5.0 g 4.5 g 6.1 g QUESTION 7 Static...
(a) Explain the relationship between the universal gravitational constant G and the acceleration due to gravity at the earth's surface g. Therefore, calculate g from G using the relationships given below. Justify the choice of units for G (Nm kg?). F= mg The mass of the earth is 5.98 x 1024 kg, it's radius is Tg = 6.38 x 10 m, and G = 6.67 x 10-11 Nm?kg (10 marks) (b) Explain, including performing the integral, how the work done...
