acts on a 2 kg mass and gives it an accoloration of 3 m/s?. What is the magnitude of the force (in Newtons)?
Recall that Newton’s Equation of Motion for a Body of Mass, m, is F = m(dv/dt). Assume the Initial Velocity of the Projectile is v0, and the Gravitational Acceleration Constant is g, where the Gravitational Force is Fg = -mg. Note that the Maximum Height will Occur at a Time, tm, when the Velocity Goes to Zero, v(tm) = 0. a) Simply Solve the Equation of Motion for the Velocity as a Function of Time, and Determine the Time it Takes the Projectile to Reach the Maximum Height, tm, As a Function of the Given Parameters. b) Include a Force of Air Resistance that is Proportional to the Velocity of the Form Fr = -kmv. Again, Solve the Equation of Motion for the Velocity as a Function of Time, by Direct Integration or by Choosing an Appropriate Ansatz Form for the Solution. Again, Determine an Expression for the Time it Takes the Projectile to Reach the Maximum Height, tm, As a Function of the Given Parameters. c) Finally, Compare the Two Results by First Checking that they Agree for a Small…
Suppose that a projectile of mass m moves in a verticalplane in the atmosphere near the surface of the earth underthe influence of two forces: a downward gravitationalforce of magnitude mg, and a resistive force FR that isdirected opposite to the velocity vector v and has magnitudek v2 (where v = |v| is the speed of the projectile;see Fig. 4.1.15). Show that the equations of motion of theprojectile are mx'' = -kvx' , my'' = -kvy' -mg,
On the moon, the acceleration due to gravity is equal to 1.67 m/s^2. How much does an astronaut weigh there, whose mass combined with his spacesuit is 171 kilograms.? Express your answer in units of Newtons.
On a spending spree in Malaysia, you buy an ox with a weight of 28.9 piculs in the local unit of weights: 1 picul = 100 gins, 1 gin = 16 tahils, 1 tahil = 10 chees, and 1 chee =10 hoons. The weight of 1 hoon corresponds to a mass of 0.3779 g. When you arrange to ship the ox home to your astonished family, how much mass in kilograms must you declare on the shipping manifest? (Hint: Set up multiple chain-link conversions.)

Which of the following statement/s is/are correct regarding the concepts of motion? According to Aristotle, a body that is stationary will continue to be stationary unless a force is applied to it. According to Aristotle, a falling body accelerates because its weight increases as it approaches Earth’s surface. According to Galileo, a body in motion along a frictionless surface does not need an external force to maintain its motion. According to Galileo, objects fall at the same rate even if one object is more massive than the other object. 1 and 2 3 and 4 1,3, and 4 1,2,3 and 4 Which of the following is a correct explanation to one of the consequences of Special Relativity?
