A5kg cat is lifted 2m into the air. how much gpe does it gain

m = mass of the cat being lifted = 5 kg

h = height to which the cat is raised into air = 2 m

g = acceleration due to gravity of earth = 9.8 m/s²

U = gravitational potential energy gained by the cat

Gravitational potential energy gained by the cat is given as

U = m g h

inserting the values in the above equation

U = (5 kg) (9.8 m/s²) (2 m)

U = (5 x 9.8 x 2) (kg m²/s²)

U = 98 J

need to see circuit to get time constant

in physics zero. in muscle fatigue could be high
