A 0.145 kg baseball is flying at a height of 2.50 m. How much potential energy
1 answer:
Gravitational potential energy is the energy stored in an object as the result of its vertical position or height. It can be calculated as its weight times the height. This is:
Where:
- W is the weight of the object
- m is the mass
- g is gravitational acceleration
- h is the height
Evaluating:
R/ The ball has 3.5525 J of potential energy.

Answer:
Kinetic energy, E = 133.38 Joules
Explanation:
It is given that,
Mass of the model airplane, m = 3 kg
Velocity component, v₁ = 5 m/s (due east)
Velocity component, v₂ = 8 m/s (due north)
Let v is the resultant of velocity. It is given by :
Let E is the kinetic energy of the plane. It is given by :
E = 133.38 Joules
So, the kinetic energy of the plane is 133.38 Joules. Hence, this is the required solution.
