please help with all of these questions!!! i’m in a big rush please please help i’m gonna cry this is so stressful Acceleration Worksheet II1. A race car reaches the straightaway on the race track going 140km/hr andaccelerates 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, howlong 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.10a) during which time interval or intervals is the speedconstant?b) During which time interval or intervals is the train'sacceleration positive?c) During which interval or intervals is its accelerationless than zero?10203040Timejn)d) During which interval is the acceleration most negative?А.В.C.D.5. For the same graph, find the average acceleration during the giventime intervals.b) 0 to 10sd) 0 to 40sa) 0 to 5sc) 15 to 20sa)b)c)6. A car slows from 22m/s to 3m/s with a constant acceleration of -2.1m/s². How longdoes this require?7.A race car travelling at +44m/s is uniformly accelerated to a velocity of +22m/s overan 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 itsdisplacement during this time?9.A car accelerates at a constant rate from 15m/s to 25m/s while it travels 125m. Howlong (in seconds) does this motion take?

The above problems are based upon equations of motion. The can be solved by using the concepts of…

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?
