ANY HELP WOULD BE APPRECIATED, THANKS

One day, you are driving your car down the highway, and you notice that you are driving well over the speed limit. You apply the brakes of the carapplying a variable stopping force, until the car slows down to a rea sonable speed of 22.4 m/s (50 mph)A computer plots the force versus time for the vehicle and then measures the area under the curve. It is found that the area is - 18.950N . The total breaking time was 5.4 s. Given that the combined mass of you and your car 1sm = 1200 kg how fast were you moving before applying the breaks? What is the average force applied by the road to the car during breaking? (Note: 1Ns=1kg* m/s)

Need help with part d and e.

Using the method of components, find the resultant of the following concurrent forces. Note: After solving for the Angle of the Resultant, you must then determine the Direction of the Resultant relative to Horizontal (positive x-axis) in a CCW (counter-clockwise direction).  Sometimes the Direction of the Resultant may be the same as the Angle of the Resultant.  However, you must always calculate both: the Angle of the Resultant (based on the Resultant triangle sketch) and then the Direction of the Resultant based on Horizontal (positive x-axis) in a CCW direction from horizontal.

When a branch contains a current source, the number of mesh equations is reduced, thus simplifying the mesh analysis technique True or false

A beam is supported by a roller at A and a pin at B. Determine the reactions at A and B when P = 15 kips. Neglect the weight of the beam.

Please give me answer for incorrect (b) one
