21.	A body leaving a certain point “O” moves with a constant acceleration. At the end of the 5th second its velocity is 1.5m/s. At the end of the sixth second the body stops and then begins to move backwards. Find the distance traversed by the body before it stops. Determine the velocity with which the body returns to point “O”?(27m, -9 m/ s) “ Pardon me for such a long question”
Answer» Explanation:At time t = 5S, u= 1.5m/s, at time t = 6S, v = 0Using v = u + at 0 = 1.5 + a x1 Therefore, a = -1.5 m/s ^2At time t= 0s, u= ?, at time time t=6s, v = 0 and a = -1.5m/s^2Using v= u+at0 = u - 1.5 x 6u = 9m/sUsing formula,S = {(u + v) x t}/2S= (9 x6)/2 = 27 mAs the body has to travel 27 m to REACH again at O, for same DISTANCE, velocity is also same but in NEGATIVE directionas at time = 0Therefore u' = -9 m/s

43.	Find the weight of 80 KG man on the surface of moon what should be his marks on the earth and
Answer» Let us make sure we understand mass and WEIGHT are not the same thing. 80 kg of mass is not the same thing as 80 N of weight. To CALCULATE weight, we use Newton's 2nd Law of Motion, which GIVES us the formula "Force = mass X acceleration". We would take the mass given, 80 kg, and multiply it times the acceleration of Earth's downward pull on that mass, 9.8 m/s/s.784 N = 80 kg x 9.8 m/s/sSo the weight on Earth is 784 newtons. Now the gravitational attraction of the moon is about 1/6 that of the Earth, or about 17%. To calculate the weight on the moon, simply multiply 784 N times .17, or 17% in decimal form:784 N x .17 = 133.28 NSo the weight of the same 80 kg mass on the moon is 133.28 N.Explanation:
