Two forces are applied to a car in an effort to move it, as shown in Figure P4.12. (a) What is the resultant vector of these two forces? (b) If the car has a mass of 3 000 kg, what accelera- tion does it have? Ignore friction.     A block of mass m 5 5.8 kg is pulled up a u 5 25° incline as in Figure P4.24 with a force of magnitude F 5 32 N. (a) Find the acceleration of the block if the incline is fric- tionless. (b) Find the accel- eration of the block if the coefficient of kinetic friction between the block and incline is 0.10.
