Answer:
Δ KE =  249158.6 kJ  
Explanation:
given data 
Truck mass  M =  1560 Kg
Truck initial speed, u = 28 m/s
mass of car m = 1070 Kg
initial speed of car u1 = 0 m/s
solution
first we get here final speed by using conservation of momentum  that is express as
Mu = (M+m) V     .......................1
put here  value we get 
1560 × 28 = (1560 + 1070 ) V
solve it we get 
final speed V = 16.60 m/s
and 
Change in kinetic energy  will be here 
Δ KE =    .................2
         .................2
put here value and we get 
  Δ KE =  
   
solve it we get 
Δ KE =  249158.6 kJ  
 
        
             
        
        
        
Answer:
See explanation below.
Explanation:
The internal energy (kinetic energy) of the milk particles increases thus warming the milk up, while the internal energy of the coffee particles reduce their initial average speed as they are imparting energy to the slow milk particles.
 
        
             
        
        
        
PE=mgh
180=0.5*10*h
180=5h
h=180/5=36 m
        
             
        
        
        
The angular momentum is m v b where b is known as the impact parameter.
<h3>What is mass?</h3>
- Mass is a physical body's total amount of matter. It also serves as a gauge for the body's inertia or resistance to acceleration (change in velocity) in the presence of a net force. The strength of an object's gravitational pull to other bodies is also influenced by its mass.
- The kilogram is the SI unit of mass (kg). In science and technology, a body's weight in a given reference frame is the force that causes it to accelerate at a rate equal to the local acceleration of free fall in that frame.
- For instance, a kilogram mass weighs around 2.2 pounds at the surface of the planet. However, the same kilogram mass would weigh just about 0.8 pounds on Mars and about 5.5 pounds on Jupiter.
- An object's mass is a crucial indicator of how much stuff it contains. Weight is a measurement of an object's gravitational pull. It is influenced by the object's location in addition to its mass. As a result, weight is a measurement of force.
Does the particle possess any angular momentum about the origin?
The angular momentum is m v b, where b is known as the impact parameter.
