Lucka's motion
Lucka set off in the afternoon to the skatepark. When coming down from a simple obstacle, she had at the beginning at time t0 = 0 s a speed of v0 = 0.6 m/s, and every second of motion the magnitude of her speed grew by 0.2 m/s. After 3 s of accelerated motion, Lucka continued along a level surface in uniform rectilinear motion, which lasted 5.0 s. Then she unintentionally went off the asphalt surface, and due to greater friction she began to move in decelerated motion, and stopped in 2.0 s.
a) Construct a graph of the dependence of the magnitude of her speed on time.
b) From the graph determine at what speed she moved during the uniform motion.
c) Calculate the distance she covered during the uniform motion.
d) From the graph determine the distance Lucka covered during the accelerated and during the decelerated motion.
e) Determine the average speed of Lucka during the entire motion.

A train moves along a track at constant speed v0 for a time t1 = 1.00 h, but then it must stop due to works on the track and waits at the place for a time t2 = 0.50 h. When it gets moving again, its constant speed is only 75% of the original speed v0. The - Ball acceleration distance
