Question

a 3-kg durian fruit was raised from the ground. How much potential energy does it have when lifted 10m/s?20m/s?30m/s?
Formula- PE=MGH
Note:
m=mass
g=acceleration (constant 9.8m/s²)
h=height​

Answer 1

Answer:

2646# joules

Explanation:

Since the work done here is raising the weight, then the total work done will be the gain of gravitational potential energy of the box.

Gravitational potential energy is given by the equation,

#"GPE"=mgh#

#m# is the mass of the object in kilograms

#g# is the gravitational acceleration, which is around #9.8 \ "m/s"^2#

#h# is the height in meters

And so, we get:

#"GPE"=180 \ "kg"*9.8 \ "m/s"^2*1.5 \ "m"#

#=2646 \ "J"#
