- A particle moves at 93 m/s when subjected to an acceleration of A = −t2/4 m/s2. How far in meters will it travel before coming to rest? Write your answer in two decimal places.A particle has a velocity of v= (3i+5j)m/s and a constant acceleration of a=(-1.5i-4.5j)m/s^2 What is its velocity after 2 seconds? Is it moving faster or slower after 2 seconds?A spacecraft starts from rest, and makes a journey to a destination 220000 km from its starting point. It does so by accelerating at a constant rate of 7.51 m/s^2 up to the midpoint of the journey, and then decelerates at the same constant rate of 7.51 m/s^2 for the second half of the journey, ending at rest. How long did the entire journey take?
- The Empire State building in New York City is 381 m tall. If a penny were dropped from rest at the height, how many seconds would it take to strike the street below? Air resistance would make a significant difference in the real world case, but ignore air resistance for now.The NEXT morning, you wake up in a strange room yet again, and this time you drop a ball from a height of 2.15 m above the floor. The ball hits the floor 0.265 s after your drop it. You guess that you must have been taken to an alien planet with gravity different from Earth s. What is this planet s g (that is, the magnitude of the acceleration due to gravity on this planet)? 61.2 m/s^2 30.6 m/s^2 45.9 m/s^2 97.9 m/s^2Suppose that in the future humans can travel to different earth like planets within our galaxy. You take a trip to a new planet with a different gravitational acceleration than earth. To test this gravitational acceleration, you decide to drop a ball a distance of 2 meters. You measure how long it takes the ball to fall 2.0 meter multiple times and take an average. The average drop time is 0.52 seconds. What is the approximate magnitude of the gravitational acceleration of the planet (in units of m/s squared)?
- A spacecraft starts from rest, and makes a journey to a destination 389000 km from its starting point. It does so by accelerating at a constant rate of 9.79 m/s^2 up to the midpoint of the journey, and then decelerates at the same constant rate of 9.79 m/s^2 for the second half of the journey, ending at rest. How long did the entire journey take? 11 hr 2 min 5 hr 31 min 3 hr 30 min 2 hr 29 minThe earth moves around the sun in an orbit that is roughly circular with a radius of 1.5 x 10^11m once every year (1 year = 3.15 x 10^7s).
