- The momentum of an object is increased by a factor of 4 in magnitude. By what factor is its kinetic energy changed? (a) 16 (b) 8 (c) 4 (d) 2 (e) 1If two particles have equal kinetic energies, are their momenta equal? a. Yes always. b. No never. c. Yes, as long as their masses are equal. d. Yes, if their masses and directions of motion are the same. e. Not unless they are moving perpendicular to each other.An object has a kinetic energy of 304 J and a momentum of magnitude 24.7 kg · m/s. Answer parts a-b.
- My last step was F=.57mg/Cos(-15.1)+(0.57 Sin (15.1) Outcome of 0.6977mg I think I found the The condition for moving a block but I don’t know what to do next.I’m confusedThree objects of different masses (1 k, 5 kgs and 10 kgs) are all launched at the same angle (45°), which do Three objects of the same mass are launched separately at different angles (30, 45 and 60). Which of the three will have the longest range provided they have the same initial velocity? Why? You can verify using the simulation. What will happen to the range and height of the projectile if you put a value of air resistance? Why? You can verify using the simulatA 250-kg flatcar 23 m long is moving with a speed of 7.0 m/s along horizontal frictionless rails. A 95-kg worker starts walking from one end of the car to the other in the direction of motion, with a speed of 3.0 m/s with respect to the car. In the time it takes for him to reach the other end, how far has the flatcar moved?
- Why is (mr)a added to the first moment equation?If two particles have equal momenta, are their kinetic energiesequal? (a) yes, always (b) no, never (c) no, except whentheir masses are equal (d) no, except when their speeds arethe same (e) yes, as long as they move along parallel lines.The three balls in the overhead are identical. Balls 2 and 3 touch each other and are aligned perpendicular to the path of ball 1. The velocity of ball 1 has magnitude v0 = 10 m/s and is directed at the contact point of balls 1 and 2. After the collision, what are the (a) speed and (b) direction of the velocity of ball 2, the (c) speed and (d) direction of the velocity of ball 3, and the (e) speed and (f) direction of the velocity of ball 1? (Hint:With friction absent, each impulse is directed along the line connecting the centers of the colliding balls, normal to the colliding surfaces.)
