A baseball of mass m1 = 0.29 kg is thrown at another ball hanging from the ceiling by a length of string L = 1.55 m. The second ball m2 = 0.81 kg is initially at rest while the baseball has an initial horizontal velocity of V1 = 3.5 m/s. After the collision the first baseball falls straight down (no horizontal velocity). What is the angle that the string makes with the vertical at the highest point of travel in degrees?
Bullets and other missiles fired at Superman simply bounce off his chest. Suppose that a gangster sprays Superman’s chest with bullets of mass m at the rate of n. The speed of each bullet is v and the angle of each bullet with respect to the plane of superman’s chest is θ. Suppose too that the bullets bounce off his chest specularly with no change in speed. Find the average force exerted by the stream of bullets on Superman’s chest. The answer is F=mn2vsin(theta). Can someone explain with steps, how did we get this?
PLEASE HELP ME ANSWER WITH SOLUTION A student (having a mass of 49 kg) falls freely from rest and strikes the ground. He comes to rest in a time of 0.387 s during the collision on the ground. The average force exerted on him by the ground is +31243 N, where the upward direction is taken to be the positive direction. From what height did the student fall? Assume that the only force acting on the student during the collision is due to the ground for this problem.
() THE FOLLOWING QUESTIONS ARE BASED ON THE INFORMATION GIVEN BELOW. Block m, of mass 15 kg moving with velocity v = 33 m/s on a frictionless plane collides block mg which is connected to block m3 by a long. massless spring with spring constant k = 7000 N/m: see the figure. Each of blocks mą and mg has a mass of 5 kg. Before the collision, blocks mą and mg are stationary and the spring is relaxed. m2 Frictionless - For parts A. B and Cassume that the collision of blocks m, and ma is completely inelastic. (Because the spring is relaxed before the collision. block mạ does not move at the instant of impact therefore (m, +m2) must move through a finite displacement before any force acts on mg and cause it to move) • For parts D and Eassume that the collision of blocks m, and m, is elastic. (Because the spring is relaxed before the collision. block my does not move at the instant of impact therefore mạ must move through a finite displacement before any force acts on mg and cause it to move)…
stretch 38. Realizing that he could not drive up a 30°, ice-covered hill because there was no friction, Sir Isaac Newton had stopped his cart, of total mass 500 kg, at the bottom. He was struck in the rear by a London stage coach, of total mass 1500 kg. trav- elling at 20 m/s. The two vehicles stuck together, with nothing breaking loose, and slid up the hill in a straight line. How far up the slope did the wreckage get before coming to rest? (SIN '70)
Two spheres collide on a horizontal surface (all velocities, before and after the collision, are in the x-y plane). Throughout this problem, assume that all forces aside from those exerted by the spheres themselves are negligible (at least in comparison). Sphere A has a mass of 0.65 grams. It has an initial speed of 6.0 m/s and an initial velocity that is oriented at an angle of θ A i = 28 degrees below the x-axis. Sphere B has a mass of 0.45 grams. It has an initial speed of 6.5 m/s and an initial velocity that is oriented at an angle of θ B i = 35 degrees above the x-axis. After the collision, sphere A has a speed of 3.5 m/s and a velocity that is directed at an angle of θ A f = 16 degrees above the x-axis. What is the final speed, in units of meters per second, of sphere B?
Blocks A, B, and C are placed as shown in the figure and connected by ropes of negligible mass through the pulleys of neglible mass and friction. Both blocks A and B have mass mA=mB= 2.5 kg each while the mass of block C is mC= 6.5kg . The coefficient of kinetic friction between blocks A and B and the surface is μk= 0.4. Initially, the system is at rest. Once released, the blocks move rightward, Find the magnitude of the acceleration of the system. Find the magnitude of the tension in the cord connecting blocks A and B. How far does block A move in the first 0.5 s (assuming it does not reach the pulley)?
In the figure, two particles are launched from the origin of the coordinate system at time t - O. Particle 1 of mass m₁ - 5.20 g is shot directly along the x axis (on a frictionless floor), where it moves with a constant speed of 10.7 m/s. Particle 2 of mass m₂ -4.50 g is shot with a velocity of magnitude 15.6 m/s, at an upward angle such that it always stays directly above particle 1 during its flight.

Two identaical billiard balls can move freely on a horizontal table. Ball A has a velocity 5 m/s as shown. And hits ball B, which is at rest, at point C defined by θ=45.

A bullet of mass m is shot into a block of mass M which hangs from a pendulum as shown. If the bullet/block combination then rises up to a height h, what is the speed of the bullet just before hitting the block? Your answer should be expressed in terms of the masses m and M, height h, and g (this arrangement is called the ballistic pendulum and can be used to determine the exit velocity of projectiles). Hint: Consider momentum conservation first, then mechanical energy conservation. M 15 f0€
A 1.21 kg block B is moving with a speed of 2.23 m/s as it strikes the 0.69 kg sphere A which was at rest. If the speed of the block was reduced to 1.21 m/s immediately after impact, compute the height (m) reached by the sphere. Round off only on the final answer expressed in 3 decimal places.
A person that has a mass of 83 kg stands in the middle of a frozen pond with a radius of 11 m.Because of the frictionless nature of the ice, they are unable to get to theother side of the pond. So, the person throws their textbook that has a mass of2.3 kg horizontally towards one side of the pond, with a speed of 7.5 m/s. How fast does theperson slide along the ice?
