A train starts from rest and accelerates uniformly until it has traveled 2.1 km and acquired a forward velocity of 24 m/s. The train then moves at a constant velocity of 24 m/s for 400 s. The train then slows down uniformly at 0.065 m/s2, until it is brought to a halt. The distance traveled by the train while slowing down is closest to A) 4.4 km. B) 4.2 km C) 4.0 km D) 3.8 km E) 3.6 km
Blood is accelerated from rest to 31.0 cm/s in a distance of 1.75 cm by the ventricle of the heart. Determine (a) the acceleration of the blood in cm and (b) the duration of the acceleration
1. A rocket accelerates upward from rest during the first stage with a constant acceleration of a1 = 95.0 m/s2 for t1 = 30.0 s. The first stage then detaches and the second stage fires, providing a constant acceleration of a2 = 50.0 m/s2 for t2 = 60.0 s. (a) What is the total distance traveled by the rocket during both stages? (b) What is the speed of the rocket after the second stage burn?
An auto accelerates from rest with acceleration a = 5 m/s2 for 10 s. It then maintains constant velocity for a period of time. Finally, in phase 3, it accelerates uniformly to rest over a period of 20 s. It travels a total distance of 1000 m. How much time does it spend traveling at constant speed? The answer is 5 s but I don't know how to get it. Show all work thanks!
