Two titanium spheres approach each other head-on with the same speed and collide elastically. The ball is in contact with the plate for 0.14s. They have equalradii, = 0.10 . Two identical charged spheres suspended from a common point by two massless strings of length l are initially a distance d (d < < l) apart because of their mutual repulsion. Two titanium spheres approach each other head-on with the same speed and collide elastically. (a) What is the mass of the other sphere? After the collision, one of the spheres, whose mass is 300 g, remains at rest. What is the mass of the other sphere? I know he uses that formula but shouldn't m1 be zero since its final v is zero because it's at rest? the relative speed of approach is equal to u1 + u2 since they are moving in opposite directions.. this is equal to the relative speed of separation which is equal to v2 - v1 . Answered: Two titanium spheres approach each | bartleby Their speeds are u1 and u2. How to solve questions on dynamics for CIE A Level Physics So this gives a resultant force. After the collision, the spheres separate with speeds v1 and v2 in the directions. The tension on the rope acting upward is greater than the weight of the man acting downward. Since the ball has the same mass the velocity before hitting the plate will be higher than the velocity after it bounces. A tutor with a demonstrated history of working in the education industry. Which equation must be correct if the collision is perfectly elastic? The diagram shows a barrel suspended from a frictionless pulley on a building. note the two objects will have the same acceleration, the man and the barrel would have covered half of the distance when his head is level with the bottom of the barrel, The same approach we use in Q2 is applicable here, m1 is the mass of the box, m2 is the mass at the other end, change in momentum = 240 160 = 80kgms-1, resultant force = change in momentum / time = 80 / 2 = 40N, Before collision, the balls move in opposite direction to each other, After collision, the balls move in the same direction, relative speed of approach = relative speed of separation, u1 u2 = v2 v1 ( when they are moving in the same direction both before and after collision), But in this case, they move in opposite direction before collision, If you look closely, u1 and v1 are in the same direction, that means, u2 and v2 are in opposite direction, that means, A ball of mass m. It is dropped onto a horizontal plate as shown in the figure below. The bottom of the barrel is 18 m above the mans head. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. shown below. Two steel spheres approach each other head - Toppr Ask See Answer.
