Answer:
Explanation:
Given
Mass of mother
Mother is released with a speed of
Assuming we need to find elastic Potential energy stored in Trampoline
Kinetic energy acquired by Mother comes from Elastic Potential Energy stored in the spring
I.e. Elastic Potential Energy=Kinetic Energy of mother
So 246.875 J of Energy is stored in the trampoline as he pull the ring
The mechanical energy of the car is
Explanation:
The mechanical energy of an object is equal to the sum of its gravitational potential energy (GPE) and its kinetic energy (KE):
E = GPE + KE
The GPE of the car is given by:
where
m = 1000 kg is the mass of the car
is the acceleration of gravity
h = 30 m is the height of the car above the ground
Substituting,
The kinetic energy of the car is given by:
where
m = 1000 kg
v = 50 m/s is the speed of the car
Substituting,
Therefore, the mechanical energy is
