Answer:
a)
b)
c)
Explanation:
From the question we are told that:
Initial speed of 1st ball
Mass of 1st ball
Mass of 2nd ball
Initial speed of 2nd ball
Final speed of 2nd ball
Angle of collision
a)
Generally the equation for law of conservation is mathematically given by
The final velocity is given as
b)
Generally the equation for law of conservation is mathematically given by
c)
Generally the equation for kinetic energy is mathematically given by
1st Ball
2nd ball
Therefore the change in the total kinetic energy of the two balls as a result of the collision is
Over 200,000 species of plants can live in rain forests
Its acceleration is 10ft/ sec
Net force acting on the car is 3 x 10^3 Newtons:
Answer: The final answer is 1,700 J
Explanation: According to first law of thermodynamics:
=Final energy-initial energy=Change in internal energy
q = heat absorbed or released
w = work done by or on the system
w = work done by the system= {Work done by the system is negative as the final volume is greater than initial volume}
q = +500J {Heat absorbed by the system is positive}
w = work done by the system = -300J
U2- 1500J= + 500J --300J
U2= 1700J
