A drag racing car’s engine produces 12,000 Newtons of thrust, pushing the car forward down the track. Frictional forces resist the forward motion of the car with a total backward force of 2010 Newtons. If the mass of the car is 820 kg, what is the acceleration of the vehicle? Round your answer to the nearest tenth. 2.45 meters per second per second
17.1 meters per second per second
12.2 meters per second per second
14.6 meters per second per second

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
