Help me please Two vechels move from rest on a straight, horizontal road to the right. The mass of the car is 1100kg and the mass of the tow truck is 4000 kg. The tow trucks engine applies a force of 15 000N. A constant friction force of 1456N is acting on the car and a constant frictional force of 4520N is acting on the tow truck respectively.
Questions
Help me calculate the acceleration of the car and the magnitude of the tension in the cable
2. Using equations of motion calculate the distance of that the car will travel in 4 seconds.
3. A create of mass 95 kg crate lies on a plank inclined at 23.2°. At this angle the crate is just about to move down the incline.
3.1 calculate the magnitude of the static friction force
3.2 the coefficient of static friction between the plank and the block
* the question does not give us the value of the coefficient or the static friction value

Two blocks, of mass 8kg and 4kg respectively, are joined with an inelastic string of negligible mass. The string runs over a frictionless pulley. The 8kg block is on a horizontal surface while the 4kg block is on an inclined plane of 40° with the horizontal. The coefficient of kinetic friction for both blocks is 0.2. The 4kg block accelerates down the slope

Questions

6.1 calculate the frictional force between the surface and the 4kg block
6.2 calculate the magnitude of the tension in the string
** please help me out I need help pls I got nowhere else to go but you.
I have just started watching your YouTube channel . I am fom south Africa. If need my email is
