1. Explain why the average velocity found in Example 1 is larger than the instantaneous velocity found in Example 2. (Hint: Sketch the graph of velocity as a function of time. Is the function increasing or decreasing? What does that tell you about how the velocities at the beginning and end of the time interval compare with the average velocity during that time interval?)...
A rocket is fired at an initial speed v0 = 141.0 m/s from ground level, at an angle θ = 33 degrees above the horizontal. Ignore air resistance.

8. A rocket is launched vertically upwards and experiences an acceleration of 4x10 m.s2 for 8 seconds. After this time, the engine is turned off and the rocket continues to rise to its maximum height. (a) Explain (using Newton's third law) why the rocket moves forward during the first 8 seconds. (2) (b) Calculate the velocity of the rocket 8 seconds after launching (2) (c) How long after launching does the rocket reach its maximum height? (2) (d) (2) At...
a.) The acceleration of a rocket fired vertically upwards t seconds after launch is 20+2t ms−2 (as a rocket burns fuel it becomes lighter, so accelerates more quickly). What is the second order differential equation for the height of the rocket. h′′= b.) What is the general solution? (Please use A as the first constant of integration and B as the second): General solution: h = c.) Use the fact that at t = 0 the rocket was on the...
I'm having problems figuring out the equations for
these questions. a detailed explanation would be great in showing
which equations was used and solving them, thank you much.

(c) An object of mass 20 kg, initially at rest, falls 15 m through the air. Its final speed is 16 m s-1. Find the energy transfer by working, for the object (due to air resistance), assuming no heat transfer or internal energy changes (d) Gas with pressure 105 Pa is contained in a cylinder of cross-sectional area 0.1 m2. One end of the cylinder...
A rocket is fired at an angle from the top of a tower of height h0 = 40.0 m. Because of the design of the engines, its position coordinates are of the form x(t) = A + B t2 and y(t) = C + D t3, where A, B, C and D are constants. The acceleration of the rocket 3.00 s after firing is a = (7.00 i + 5.00 j) m/s2. Take the origin of coordinates to be at...
