- A van had a small light in the ceiling of the cargo bay. When the van is accelerating east at a rate of 2.99 m/s^2, the light bulb rattles loose and falls to the floor. Determine the acceleration relative to the earth and its direction and the acceleration relative to the van and it’s direction.Vector A had a magnitude A=5.7 and direction theta= 77.9 degrees measured clock wise from the -y-axis.

- An airplane takes 5 hours to travel a distance of 4500 miles with the wind. The return trip takes 6 hours against the wind. Find the speed of the plane in still air and the speed of the wind.As seen from the Earth, the distance from Earth to the Sunis 1.50 × 10¹¹ m. A certain particle travels that distance in only 9.36 min. Answer the three questions below, using three sig figs. Part A - What is the speed of the particle, v, as seen from Earth?

All he has to use is a baseball, a stopwatch, and a friend on the ground below with a long measuring tape. Bob is a pitcher and knows that the fastest he can throw the ball is about vo = 33.7 m/s. Bob starts the stopwatch as he throws the ball, with no way to measure the ball's initial trajectory, and watches carefully. The ball rises and then falls, and after t₁ = 0.710 s the ball is once again level with Bob. Bob cannot see well enough to time when the ball hits the ground. Bob's friend then measures that the ball hit the ground x = 123 m from the base of the cliff. How high above the beach was the ball when it was thrown? initial height: X 1₁ m

By setting his camera to record 10 frames per second and noting down each particle's 2D displacement for each recorded frame, he managed to obtain the following mean-displacement vs time graph: 1600 1400 1200 2 1000 V 800 600 400 200 20 40 60 80 100 120 140 Time (s) a. Use the above mean-displacement graph to roughly approximate the diffusion coefficient D of the dust particles with units of um? /s. b. From the diffusion coefficient estimate in a), calculate the root mean- square displacement expected between each consecutive frame? c. Are the diffusion coefficient D and mean-square displacement calculated reasonable for a microscopic particle, or did Bob make a mistake in his calculations? Mean-square disp.
