The acceleration of a particular sports car is proportional to the difference between 250 km/h and the velocity of this sports car. If this machine can accelerate from rest to 110 km/h in 10 s, how long will it take for the car to accelerate from rest to 220 km/h? It would take second(s).Suppose that you are strandedyour rocket engine has failedon an asteroid of diameter 2 miles, with density equal to that of the earth with radius 3,960 miles. If you have enough spring in your legs to jump 3.5 feet straight up on earth while wearing your space suit, can you blast off from this asteroid using leg power alone? Note that the ft escape velocity on Earth is about 36,680 E' Select the correct choice below and ll in the answer box to complete your choice. (Type integers or decimals rounded to two decimal places as needed.) ft Yes, you can blast off because the escape velocity of the asteroid, E, is less than your initial velocity when jumping, . ft No, you cannot blast off because the escape velocity of the asteroid, E, is greater than your initial velocity when jumping
