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.

Two smooth disks A and B each have a mass of 0.5 kg. Both disks are moving with the velocities shown when they collide. Suppose that (vA)1 = 9 m/s , (vB)1 = 8 m/s. The figure shows two discs, A and B, moving toward the origin of a horizontal xy-plane, where they collide, so that their common tangent lies on y-axis. Disk A moves in negative x-direction with velocity left-parenthesis v subscript A right-parenthesis subscript 1. Block B moves from the third quarter with velocity left-parenthesis v subscript B right-parenthesis subscript 1, directed along an inclined line with a slope of four-thirds. Determine the coefficient of restitution between the disks if after collision B travels along a line, 30∘ counterclockwise from the y axis.

A thin rod of length 2L and mass M lies flat on a frictionless plane. It is not hinged (attached) to anything. A small ball of mass m, traveling with velocity vo, strikes the rod at a distance h from the rod's center of mass. The collision is elastic. The ball continues to move along the original line of motion after the collision. The rod moves on the plane and rotates around its center of mass. After the collision, we want to determine the rod translational velocity, the rod angular velocity and the ball final velocity. a) Write three equations to find these three unknowns based on m, M, L, h and vo. Do not try to solve the equations. b) If the collision were inelastic and the rod was hinged at its center CM, what would be the rotational angular velocity of the system after the collision?
