A Car Mass 1100 Kg Is Traveling – 2 Momentum, p The linear momentum p of an object is equal to the product of the object’s mass m and its velocity v: Linear momentum is a vector quantity pointing in the same direction as the velocity. SI unit of acceleration: kilogram · meter/second = (kg · m/s)
3 Impulse, J The root of the force J is equal to the product of the average force and the time interval over which the force acts Dt: The base is a vector quantity and has the same direction as the average force. SI unit of impulse: newton · second = (N · s) = kg. m/s Force and momentum, both have the same unit.

When a net force acts on an object, the net force is proportional to the change in position of the object:

5 11. Suppose a boy drives a truck on a sidewalk, and he exerts a force of 4000 N on the truck for s. (a) What motion does this force cause? (b) Find the final velocity of the car if the initial velocity of the car is 2.80 m/s and the mass of the car and driver is 200 kg. Neglect friction between the car and the floor.
Method-1: Knowing the maximum power () and contact time (Dt), it shows that = method-2: Effective = area under photoelectric force.
Unlike rain, hail usually does not subside once it hits the ground. On the contrary, the hail fell on the roof of the car. If hail falls instead of rain, will the force on the roof be less, equal, or greater? Answer: The highest
9 Example A baseball (m = 0.14 kg) has an initial velocity v0 = -38 m/s as it approaches the bat. We chose the wrong path. The bat experiences a maximum force greater than the weight of the ball, and the ball leaves the bat with a final velocity vf = +38 m/s. Determine the movement of the bat against the ball.

10 Definitions of Constraints Internal constraints restrict the interaction of system components with each other. Foreign forces used the elements through agents outside the system. An isolated system is a system in which the vector sum of the external forces acting on the system is not equal to zero.
A freight train is assembled at the switching yard and the picture below shows two cars. Car 1 has mass m1 = 65 × 103 kg and is moving at speed v01 = m/s. Car 2 with mass m2 = 92×103 kg and speed v02 = +1.3 m/s passes and joins car 1. Neglecting torque, find the constant speed vf of the motors after they are combined.
13 EXAMPLE: Skaters Starting at recess, two skaters “push” each other on smooth ice with poor friction. As shown in the figure, one is female (m1 = 54 kg) and the other is male (m2 = 88 kg). Part b of the diagram shows that the woman is walking at a speed of vf1 = +2.5 m / s. Find the man’s vf2 “recovery” rate.
14 Collisions are often classified according to the change in the total kinetic energy of the system during the collision: 1. Elastic – a collision in which the total kinetic energy of the system after the collision is equal to the total kinetic energy before the collision. 2. Inelastic collision – one in which the total kinetic energy of the system before and after the collision is not equal; if the objects stick together after the collision, the collision is said to be completely irreversible.

Football 18: On third down with less than one yard left, a 70-kg Minnesota Viking quarterback is moving at 6 m/s and a 90-kg San Francisco 49er is moving forward. . 5 m/s you. Can you guess the outcome of this game?
19 Car Collision Problem A car with a mass of 850 kg and a speed of 16 m/s is approaching the intersection as shown. A small car weighing 1200 kg traveling at a speed of 21 meters per hour on the same road. A car and a small car collided. Assuming that external forces are negligible, find the velocity (vf) and direction (θ) of the decay after the collision.
