a 5 kg fish swimming at a speed of 1m/s swallows an absent minded 1 kg fish swimming toward it at 4 m/s. the speed of the larger fish after lunch is?
help?! 10. Consider a big fish on the hunt for its lunch. The big fish has a mass of 10kg and it is swimming at 2m/s towards its lunch-the little fish (2kg) who is just sitting still resting. a. What will be the speed of the large fish immediately after lunch? 10kg 2kg 2m/s. Rest b. What would be the speed of the large fish if the small fish was swimming towards the large fish at 3m/s when he was...
I need solutions that are detailed for these introductory physics questions please! Name: ID: 1. Consider a fish that swims toward and swallows a smaller fish. If the larger fish has a mass of 5kg and the smaller one has a mass of 1-kg fish, what is the velocity of the larger fish immediately after lunch if its velocity before lunch was 1 m/s to the right and if the smaller fish was moving to the left at a velocity...
Object A moves at a speed v and collides with object B, initially at rest as shown to the right. Both objects have the same mass. Assume the surface on which the objects move to be frictionless. If the collision is completely inelastic, the speed of object A after the collision A) O B) v/4 C) v/2 D) v E) 2v D) v E) 2v If the collision is elastic, the speed of object A after the collision is A)...
Problem 4 (1 points) A proton (P) of mass 1.01 u (unified atomic mass unit) traveling a speed of 3.5x109 m/s has an elastic head on collision with a helium (He) nucleus (mwe = 4.00u) initially at rest. What are the velocities of the proton and helium nucleus after collision? Assume the collision takes place in nearly empty space. (Hint: conservation of linear momentum, elastic collision)
part B: please show every step. mass one = 3ka is initially travelling w/ a speed of umis & runs into a mass two, that is initially at I rest. After the collision, the mass one, has reversed - clirection, of is traveling with a speed 2 m/s IP, = -6 kam/s Assume mass two qka. Is this an P2 = 18 kgm/s elastic or inelastic collision ? Give a written or Mathematical Argument to justify He answer
Billiard ball A of mass mA = 0.125 kg moving with speed vA = 2.80 m/s strikes ball B, initially at rest, of mass mB = 0.140 kg . As a result of the collision, ball A is deflected off at an angle of θ′A = 30.0∘ with a speed v′A = 2.10 m/s, and ball B moves with a speed v′B at an angle of θ′B to original direction of motion of ball A. Part C Solve these equations...
A pendulum bob, with mass 1.60 kg, is held at rest initially in a horizontal position as shown. The string has negligible mass and a length of 1.20 m. The bob is then released from rest. It swings down and collides with a block of mass 2.40 kg initially at rest. Ignore air resistance. a) Use the Principle of Conservation of Mechanical Energy to find the speed of the pendulum bob just before the collision. b) (The bob collides with...
i need just this question answered 7 Sho ..6.20 Screen 019-10 Sphere A, of mass 0.600 kg, is initially moving to the right at 4.00 m/s. Sphere B, of mass 1.80 kg, is initially to the right of sphere A and moving to the right at 2.00 m/s. After the two spheres collide, sphere B is moving at 3.00 m/s in the same direction as before. (a) What is the velocity (magnitude and direction) of sphere A after this collision?...
1 Elastic collision A bumper car of mass m1 = 300kg is initially moving to the right at velocity V1, before = 8m/s and collides head-on with another bumper car of mass m2 = 200kg that is motionless, V2, before = 0. After the collision, the heavy bumper car is moving at a speed of v1,after = 1.6m/s. (a) (5 pts) Calculate the total kinetic energy before the collision (b) (5 pts) Calculate the kinetic energy of the heavy car...
