A lunar lander is making its descent to Moon Base I . The lander descends slowly under the retro-thrust of its descent engine. The engine is cut off when the lander is 5.0 m above the surface and has a downward speed of 0.8 m>s.With the engine off, the lander is in free fall. What is the speed of the lander just before it touches the surface? The acceleration due to gravity on the moon is 1.6 m/s2.

- You throw a baseball directly upward at time t=0 at an initial speed of 12.1 m/s. What is the maximum height the ball reaches above where it leaves your hand? Ignore air resistance and take g=9.80 m/s2 At what times does the ball pass through half the maximum height?arrow_forwardSuppose you throw an object from a great height, so that it reaches very nearly terminal velocity by time it hits the ground. By measuring the impact, you determine that this terminal velocity is -49 mi sec.A. Write the equation representing the velocity v(t) of the object at time t seconds given the initial velocity v0 and the fact that acceleration due to gravity 9.8 m/sec2. (Here, assume you're modeling the falling body with the differential equation dy/dt = g-kv, and use the resulting formula or v(t) found in the Tutorial. Of course, you can derive it if you'd like.)B. Determine the value of k, the "continuous percentage growth rate" from the velocity equation, by utilizing the information given concerning the terminal velocity.C. Using the value of k you derived above, at what velocity must the object be thrown upward if you want it to reach its peak height after 3 sec?

- A jet plane comes in for a landing with a speed of 120 m/s. The length of the runway is 500 m. From the instant the plane touches the runway, what is the magnitude of the acceleration needed to stop within the runway? Write your answer in terms of m/s2.arrow_forwardYou and a couple friends have entered a diving competition during your March Break. You will be diving from the 5m (highest) platform at the University of Toronto Varsity Pool. You know that your acceleration while falling will be the acceleration of gravity, 9.81m/s2 , but you’re wondering about the rate at which you’ll be slowing down once you enter the water – and really – will it hurt. Science has shown us that 2 times the acceleration of gravity is exhilarating (like a roller coaster), but at 3 times the acceleration of gravity most people are uncomfortable. You estimate that it will take 0.64s to stop once you enter the water. You and your friends decide to figure out what your acceleration will be before you commit to making the dive.a) What will your acceleration in the water be?b) Will it hurt?arrow_forwardA rocket starts from rest and moves upward from What is the height of the rocket above the surface of the earth at t = 10.0 s? the surface of the earth. For the first 10.0 s of its motion, the vertical acceleration of the rocket is (2.80 m/s) t, where the +y- given by ay direction is upward. Express your answer with the appropriate units.arrow_forward

Answer between −180◦ and +180◦.arrow_forwardIf a stone is dropped from the top of a tower with initial release velocity equal to zero, it falls a distance d in time t given by d = ½ gt2 where g is acceleration due to gravity (g = 9.8 m/s2). Its speed v at time t is given by v = gt. Suppose you go to the top of a tower and drop a stone. It hits the ground after 4.5 seconds. By how much does it drop in 1 second?
