The position of a particle moving along an x axis is given by x = 2012- 6³, where x is in meters and t is in seconds. (a) Determine the position of the particle at t = 3.0 s. 18 m

Please answer Question 2 parts b-e, previous part is answered

could i get a recheck on part b please

Need help on part c

1 A block is placed on an elevator platform that moves downward with decreasing speed. Consider the time interval At, in which the speed of the platform changes from v, to zero. Decreasing speed (from v, to zero) Block a. In the space provided, sketch a free-body diagram for the block. b. Is the net work done on the block positive, negative, or zero? Platform For each force on the free-body diagram, state whether the work done on the block by that force is positive, negative, or zero. Explain. Free-body diagram for block Rank the works you identified above in order of decreasing absolute value. Explain. c. Consider reference frame R, moving downward with constant speed v.. In reference frame R: Direction of acceleration Direction of i. In the spaces provided, draw arrows to indicate the direction of the velocity and the acceleration of the block in reference frame R during the interval At,. Explain. velocity of block of block ii. In reference frame R: • is the block speeding up,…

I would like a step by step process with formulas used and free body diagram, along with therefore statements

Please show all work and answer all parts

Mike's car, which weighs 1,000 kg, is out of gas. Mike is trying to push the car to a gas station, and he makes accelerate 0.05 m/s/s. Using Newton's Second Law, you can compute how much force Mike is applying to the car. If the gas station is 200 meters away and the friction force against him is exactly equal to the force applied in part a, how much work did Mike do?

The small cart has a speed 16 ms at point A. Neglecting friction, determine its speed at point B. Round your result to the nearest integer. 1.8 m B

Please show your work, thank you :)
