Answer #1

10. A bullet of mass M1= 0.4 Kg
moving with initial velocity V1i= 800
m/s gets embedded into a block of wood of mass
M2= 3.6 Kg that was initially at rest
(V2i=0). The block is attached to a
spring having spring constant K=400 N/m. After
making the inelastic collision, the bullet-block
combination slides on a horizontal frictioless surface and
compresses the spring.
Part A
The amount of compression distance delta
X by which the spring gets compressed by the bullet-block...

A car of mass m1 = 2000.0 kg is moving at speed v1i = 20.0m/s
towards East. A truck
of mass m2 = 5000.0 kg is moving at speed v2i = 10.0m/s towards
North. They collide at an
intersection and get entangled (complete inelastic
collision).
1. What is the magnitude and direction of the final velocity of the
entangled automobiles?
2. How much kinetic energy is lost in the collision. That is,
calculate the change in the
kinetic energy of...

e. What is the average force acting on the stationary car by the
moving car during the collision?
f. What is the total kinetic energy before the collision?
g. What is the total kinetic energy after the collision?
h. What is change in momentum?
i. What happens to the lost kinetic energy? Explain clearly
j. Is this an...

2a) Mass 1 is moving at 6 m/s in the +x
direction and it collides in a perfectly
elastically with mass 2 of 2 kg
moving at 15 m/s in the -x direction. They
collide for 0.3 seconds, and the average
force on mass 1 is 148 N in the -x direction. What is
the mass of mass 1 in kg?
2b) Mass 1 is moving at 3 m/s in the +x
direction and it collides
inelastically with mass 2...

A railroad car of mass 2.50 ✕ 104 kg moving at 3.40
m/s collides and couples with two coupled railroad cars, each of
the same mass as the single car and moving in the same direction at
1.20 m/s.
(a) What is the speed of the three coupled cars after the
collision?
(b) How much kinetic energy is lost in the collision?

A 2500 kg car moving east at 10.0 m/s collides with a 3000 kg
car moving north. The cars stick together and move as a unit after
the collision, at an angle of 47.0° north of east and at a speed of
6.66 m/s. Find the velocity of the 3000 kg car before the
collision. m/s north

Mass 1 is moving at 3 m/s in the +x direction and it collides
inelastically with mass 2 of 16 kg moving at 13 m/s in the + x
direction. 138 Joules of KE is lost in this collision. What is the
average force on mass 1 if the collision takes place in 0.3
seconds? Answer in Newtons.
