- A spacecraft starts from rest, and makes a journey to a destination 355000 km from its starting point. It does so by accelerating at a constant rate of 14.76 m/s^2 up to the midpoint of the journey, and then decelerates at the same constant rate of 14.76 m/s^2 for the second half of the journey, ending at rest. How long did the entire journey take? a. 3 hr 20 min b. 2 hr 43 min c. 1 hr 56 min d. 6 hr 41 minarrow_forwardYou are driving along Lawrence Ave. at 60 km/h.

- George walks to a friend’s house. He walks 750 meters North, then realizes he walked too far. He turns around and walks 250 meters South. The entire walk takes him 13 seconds. What is his speed per second? What is his velocity in meters per second? I know the answer for the second one, velocity in meters per second is 38.46 m/s. But I'm really confused because since velocity = displacement/time. Displacement = final position - initial position. How can it equal 38.46 m/s since it should be 250 - 750 / t, not 750 - 250 / t? Please show the formula you use and explain it in an easy to understand way.arrow_forwardMany handicapped individuals struggle using electric wheelchairs. Researchers used Bayes' rule to assess a “intelligent” robotic controller that attempts to record a wheelchair user's intent and assist in navigation. Consider the situation below. A wheelchair user may either (1) turn abruptly left and approach a door, (2) go straight to the opposite side of the room, or (3) turn slightly right and halt at a table. D (for door), S (straight), and T (for time) (for table). P(D) = 0.4, P(S) = 0.25, and P(T) = 0.35. The wheelchair has a joystick operated by a robot. The user directs the joystick straight 50% of the time while going through the door, 30% of the time when going straight, and 25% of the time when going to the table. What is her most likely destination, calculate based on P(D|J), P(S|J) and P(T|J)?arrow_forwardOn the Apollo 14 mission to the moon, astronaut Buzz Aldrin hit a golf ball with a golf club improvised from a tool. The free-fall acceleration on the moon is 1/6 of its value on earth. Suppose he hit the ball with a speed of 29 m/sm/s at an angle 22 ∘∘ above the horizontal. a. how long was the ball in flight in seconds? b. how far did it travel in meters? c. If there was no air resistance, how much farther would it travel in meters on the moon than on earth?arrow_forward

During what time intervals is the object speeding up? slowing down? d. During what time intervals is the acceleration positive? Negative? Zero? from t = 4 to t = 11 s? e (sec) iparrow_forwardAnswer the following question(s): A student sees her physical science professor approaching on the sidewalk that runs by her dorm. She gets a water balloon and waits. When the professor is 2.0s from being directly under the window about 11m from the sidewalk, she drops the balloon. Finish the story. Instructor Note: There are several ways to reach the correct answer. I generally solve for time to determine if balloon will hit the professor or not based on the given scenario. A formula to use is ?=12??2d=12gt2?d = 1 2 g t 2 where d = distance g = gravitational constant of 9.8 t = timearrow_forwardThe prompt is in the image attached. The questions I need help are:a) Evaluate the acceleration at t=1.0 s. Express your answer in m/s^2 in 2 significant figures.b) Evaluate the acceleration at t=11s. Express your answer in m/s^2 in 2 significant figures.Thank you!arrow_forward
