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.

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
