please help with question number one 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

How do you calculate the miles you are getting per gallon of gasoline if you record the mileage readings from your car’s odometer each time you fill up the gas tank? Two odometer readings should be inputted, one reading is before you fill up the gas tank, and the second reading is when you refill the gas tank. The third input is the quantity of gallons of gasoline purchased when the gas tank is refilled. After inputting these 3 values, calculate and output: The miles traveled between gas refills The average miles per gallon based on the miles traveled and the amount of gasoline purchased after the time the gas tank is refilled (Use sequential structure)

Consider the diagram below. Nine unique, labeled locations are provided on a grid. Each square on the grid represents a 20-meter x 20-meter area. Rightward on the grid is in the eastward direction and upward on the grid in the northward direction. Use the grid in answering the next few questions. Suppose that a person starts at position A and walks to position E and then to position G. Fill in the table below to indicate the east-west and the north-south components of the individual legs of the walk and the components of the resulting displacement. Make the measurements off the grid. Finally, use the Pythagorean theorem and SOH CAH TOA to determine the magnitude and the direction of the resulting displacement.
