A small block (2.25kg) travels along a frictionless path at a speed (6m/s) before it reaches a frictionless semi circular path with a radius of 0.5m. 1) at point A, what is the force exerted by the track on the block? 2) the bottom of the track has a length of 15m with friction. Determine the coefficient of kinetic friction between the block and the bottom of the portion of the track if the block just makes it to point B before coming to rest.
A 200 N block slides from rest down a plane inclined 25° to the horizontal. Assuming =0.20, what will be the speed of the block after 5 seconds?
QUESTION TWO: A car is capable of reaching 27 km/h from rest in 4 seconds on a level road against resistances amounting to 4% of the vehicle mass. If the car has a mass of 1200 kg, calculate the minimum distance over which it could reach 36km/h from rest if towing a caravan of mass 700 kg. Assume the tractive effort to be constant and the tractive resistance to be the same rate for car and caravan.
This question is similar to the question above but read and calculate carefully. The situation has changed and the numbers have changed. Bonita Cart Bonita is again pulling a cart to the right. The cart used to be tied to a wall but now the rope has broken so the cart rolls over the horizontal floor without friction. Assume that the only forces on the cart are tension forces (including the force from Bonita), normal forces, and gravity with g = 9.81 m/s?. Bonita's shoes do not slide over the floor. Bonita has a mass of 52 kg. The cart has a mass of 45 kg. The mass of the rope is small enough to be ignored. Bonita is pulling the cart with a constant force of 283 newtons. Calculate the magnitude of the force that the cart exerts on Bonita. Note that the magnitude of a force is a positive quantity.

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.
You have been chosen as the test subject for the newest attraction at Canada’s Wonderland. This attraction is a single-person roller coaster ride that has a 25.0 m drop followed by a collision with a plunger attached to a large spring that brings the ride to rest. The plunger/spring mechanism is composed of a large spring with a mass of 62.5 kg made of pure iron..The cart has a mass of 75.0 kg and starts at rest from the top of the track. To determine the total mass of the cart during the ride you must add your mass to the system. As the cart moves down the track it has been determined that friction in the wheels and axles results in the production of 12750 J of thermal and sound energy combined. The plunger/piston at the bottom of the device has been designed to stop the cart with a maximum acceleration of 5.00 g’s (i.e. 49.0 m/s2). Before you start: What is your approximate mass in kilograms? MY MASS IS 82 kg In order to stop the ride, the cart collides with the…
