Let's assume the rocket has a rest length of 57 m and the hangar has a rest length of 51 m. Additionally, assume the relative velocity between H & R (the speed they see the other moving at) is 0.61c. How long is the rocket according to H? Rocket length according to H = How long is the hangar according to R? Hangar length according to R =

A projectile isfired with an initial velocity of vo (m/sec) upward at an angle (0) with the horizontal. Find the horizontal distance Covered before the projectile returns to its original level. Also determine the maximum height attained by the projectile- h=? max [Hint] É x=2

Consider a rocket at take off. Assume that the rocket is moving vertically for the time in question here. The acceleration (in m/s²) as a function of time is given by a(t) = 1.5 + 0.47 t + 0.10 t² (with t in seconds and the take off at t=0). What is the speed of the rocket at 16 s (in m/s).

From rest a balloon begins to rise. the Balloon experiences a lift due to a buoyant force of 8000 N. 1. Total massof the balloon is 600kg. Find Acceleration. 2. The balloon rises a distance of 10m and loses a mass of 50 kg after a weight is thrown off. Find the acceleration of the balloon after this weight loss 3. Find the initial velocity of the mass in the vertical direction at the timeof the jump. 4. After falling 10 m, find the mass' final velocity as it comesinto contact with the ground. 5.What is the total time the mass takes to hit the ground? 6. Find the heightof the balloon when the mass hits the ground 7. The mass lands 3 m from the baloon, find the horizontal velocity required to land 3m from the balloon. 8. Since the balloon exeperiences equal forces when the mass is thrown off, what is the horizontal velocity the baloon experiences during this act and how far does the balloon travel when the mass comes into contact with the ground?

a) What force balances gravity, and what is the name of the resulting equation below? ốp -g
