pls send me answer of this question all the parts pls and i will rate you sure, pls solve a,b,c and d and also a and b A 200-kg dragster (racing car) exerts a constant force of 4000 N during a race. The coefficient of kinetic friction between the tires and the pavement is .15. If the drag strip is 1000 m long, determine:a. The net force on the dragster. b. The acceleration of the dragster. c. The time it takes for the dragster to finish the race.d. The dragster's velocity at the end of the race.The dragster now needs to slow down, so it opens a parachute. The force of air drag is 3500 N. The driver also locks the brakes of the dragster, and the coefficient of kinetic friction becomes .75. Determine:a. How long it will take to stop the dragster.b. The distance the dragster travels while stopping.
- H1. A wooden block of mass m is pushed over a floor in a straight line in the x direction with a constant velocity vo > 0. At time t = 0, when the block is at position x = 0, it is no longer pushed and the block experiences only a constant sliding friction force F in the negative x-direction until it comes to rest. (i) Write down the equation of motion of the block for t > 0. Calculate the time, t, at which the block comes to a stop and also find the distance, d, travelled by the block from the time when the pushing is stopped to the time when it comes to rest. (ii) Calculate the work done by the friction force from x = 0 to x = d, and then show that it is equal to the change in the kinetic energy of the block.
