(c) Draw the following graphs: position versus, velocity versus time,...
A subway train starts from rest at a station and accelerates at a rate of 1.60 m/s2 for 10.0 s. It runs at a constant speed for 50.0 s and slows down at a rate of 3.20 m/s2 until it stops at the next station. How far apart are the two subway stations? A 40 m B 80 m C 800 m D 920 m E None of the above.
A subway train starts from rest at a station and accelerates at a rate of 1.95 m/s2 for 15.0 s. It runs at constant speed for 74.0 s and slows down at a rate of 3.20 m/s2 until it stops at the next station. Find the total distance covered. 2.51 km 2.52 km 2.53 km 2.56 km
A car starts from rest at a stop sign. It accelerates at 3.7 m/s2 for 6.5 s , coasts for 1.9 s , and then slows down at a rate of 2.5 m/s2 for the next stop sign. How far apart are the stop signs?
A car starts from rest at a stop sign. It accelerates at 4.6 m/s2 for 7.4 s , coasts for 1.5 s , and then slows down at a rate of 3.2 m/s2 for the next stop sign. how far apart are the stop signs?
30. A truck on a straight road starts from rest and accelerates at 2.9 m/s? until it reaches a speed of 32 m/s. Then the truck travels for 33 s at constant speed until the brakes are applied, stopping the truck in a uniform manner in an additional 20.0 s. (a) How long is the truck in motion? (b) What is the average velocity of the truck for the motion described?
