# A train travelling along a straight track starts from rest at point A and accelerates uniformly to 10 m si in 20 s. It travels at this speed for 60 s, then slows down uniformly to rest in 40 sat point C. It stays at rest at C for 30 s, then reverses direction, accelerating uniformly to 5 ms. in 10 s. It travels at this speed for 30 s, then slows down uniformly to rest in 10 s when it reaches point B. 1. Plot a graph of the motion of the train. II. Use your graph to calculate: III. the train's displacement from point A when it reaches point C IV. the train's displacement from point A when it reaches point 13 V. the train's acceleration each time its speed changes.   ### Another question on Physics Physics, 22.06.2019 03:30
How do basketball players jump straight up into the air? how do basketball players jump straight up into the air? the player pushes down on the floor, which pushes back up on him. the player accelerates upward because the force of his push is greater than the force of gravity. the player pushes down on the floor, which pushes back up on him. the player accelerates upward because the force of his push is equal to the force of floor's push. the player pushes down on the floor, which pushes back up on him. the player accelerates upward because the force of his push is equal to the force of gravity. the player pushes down on the floor, which pushes back up on him. the player accelerates upward because the force of his push is greater than the force of floor's push.
