A ball of mass 250 g is thrown with an initial velocity of 25 m/s at an angle of 30 with the horizontal direction. Ignore air resistance. What is the momentum of the ball after 0.2 s? (Do this problem by finding the components of the momentum first, and then constructing the magnitude and direction of the momentum vector from the components.)
If a rainstorm drops 1 cm of rain over an area of 10km2 in the period of 1 hour, what is the momentum of the rain that falls in one second? Assume the terminal velocity of a raindrop is 10 m/s.
Two identical objects (such as billiard balls) have a one-dimensional collision in which one is initially motionless. After the collision, the moving object is stationary and the other moves with the same speed as the other originally had. Show that both momentum and kinetic energy are conserved.
In an elastic collision of two particles with masses m1 and m2, the initial velocities are u1 and u2 = u1. If the initial kinetic energies of the two particles are equal, find the conditions on u1/u2 and m1/m2 such that m1 is at rest after the collision. Examine both cases for the sign of .
What external force is responsible for changing the momentum of a car moving along a horizontal road?
Ball having mass 9kg and velocity 7.5m/s travels to the east. Impulse given at point O, makes it change direction to north with velocity 8.6 m/s. What is the direction of the given impulse, measured in unit of degrees, if the angle is defined as between the horizontal direction (east) and the impulse?
Two balls moving in opposite directions have velocities v1ix= 14ˍm/s and v2ix = -8.4ˍm/s . If their masses are m1 = 3.3ˍkg and m2 = 6.9ˍkg, respectively, and if their collision is perfectly elastic, then predict the velocity of each ball following the collision.
Initially resting in the xy coordinate plane's center, an item erupts into three parts. Immediately after the explosion, a piece of mass 2m travels with a velocity of v in the negative x direction, while another piece of mass 3m moves with the same velocity in the negative y direction. The third component has a mass of 4m. i. immediately after the explosion, what is the magnitude of the third particle's velocity in terms of the above variables? Beginning with momentum conservation is a good place to start. ii. Immediately after the explosion, what is the direction of motion of the third piece (as an angle relative to the positive x axis)?
If you knew the position of an object precisely, with nouncertainty, how well would you know its momentum?
Starting from Newton’s second law of motion, prove that impulse imparted on an object is equal to the change in momentum its momentum. Two masses m1 and m2 with a separation distance of d, attract each with a force F. What is the relationship between the F, m1, m2, and d? By what factor will the force of attraction change if the distance is quadrupled? A 400 kg object moving at a speed of 5 m/s to the right collides with a 600 moving at 2 m/s to the left. After the collision, the 600 kg object moves to the right at a speed of 3 m/s. Determine, the velocity of the 400 kg object after the collision
Two cars, of mass 2 kg and 1 kg, approach each other heads-on with the same speed 3 m/s, as shown in the figure above. When the carts collide, they hook together. Assuming positive momentum is to the right, which of the following best represents the momentum of the cart of mass 1 kg as a function of time before and after the collision?
since the initial mass is m, the first piece m1 = m/4, shouldn't the other two masses sum: m2 + m3 = (3/4)m? (mass = positive scalar) Perhaps solving by using conservation of momentum, initial momentum = 0, defining the ecuations for final momentum on x and y axis, and solving from there? thanks
