Question

3. The leaning Tower of Pisa is 45 m high. A mass of 4 kg is dropped from the top. Calculares
potential energy at the
top-​

Answer 1

Answer:

given: mass=4kg, height=45m and considering g=10m/s^2

since,P.E.=mgh

therefore,P.E.=4×10×45

P.E.=1800

Explanation:

plz mark me as brainliest

Answer 2

Explanation:

Given,

Height, h = 45m

Mass, m = 4kg

Acceleration due to gravity = 9.8 m/s^2

PE = ?

Potential energy = mgh = 4 × 9.8 × 45 = 1764 J
