hello please help with questions 5 through 9 and i also sent a picture of the graph it’s on number 4
Acceleration Worksheet II 1. A race car reaches the straightaway on the race track going 140km/hr and accelerates at a rate of 3.5m/s²for 6.2 seconds. a) what is the car's initial speed in m/s? b) What is the car's speed at the end of the 6.2 seconds? c) How far did the car travel in that time? 2. A fighter jet covers a distance of 895m while accelerating from 22m/s to 35m/s. How long (in seconds) did this take to happen? 3. A proton is accelerated in a linear accelerator. If the accelerator is 0.80km long, how long does it take to get the proton from rest to 2.5 x 10*m/s? 4. Using the graph at right, answer the following questions. 10 a) during which time interval or intervals is the speed constant? b) During which time interval or intervals is the train's acceleration positive? c) During which interval or intervals is its acceleration less than zero? 10 20 30 40 Timejn) d) During which interval is the acceleration most

negative? А. В. C. D. 5. For the same graph, find the average acceleration during the given time intervals. b) 0 to 10s d) 0 to 40s a) 0 to 5s c) 15 to 20s a) b) c) 6. A car slows from 22m/s to 3m/s with a constant acceleration of -2.1m/s². How long does this require? 7.A race car travelling at +44m/s is uniformly accelerated to a velocity of +22m/s over an 11s interval. What is its displacement during this time? 8.A rocket travelling at +88m/s is accelerated to +132m/s over a 15s interval. What is its displacement during this time? 9.A car accelerates at a constant rate from 15m/s to 25m/s while it travels 125m. How long (in seconds) does this motion take?
