please help with questions 4 through 9 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 ighter 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, howTong 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.1210a) 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?102030Fierie ja)d) During which interval is the acceleration most negative?A.в.C.D.2. For the same graph, find the average acceleration during the giventime intervals.a) 0 to 5sc) 15 to 20sb) 0 to 10sd) 0 to 40sa)b)c)d)0. 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 1ls 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?2001 m9.A car accelerates at a constant rate from 15m/s to 25m/s while it travels 125m. Howlong (in seconds) does this motion take?
