Manita carries a box of mass 40 kg. What is the weight of the box?( g=9.8m/s)​

Mathematics
1 answer:
Lilit [14]2 years ago
8 0

Explanation:

Mass of boy = 40 kg

Mass of box = 20 kg

Total mass = 60 kg

Initial potential energy = 0 (since height would be 0 initially)

Final potential energy = mgh

Taking g as 10 m/s²,

=> 60 × 10 × 15

= 9,000 J

So, work done = final potential energy - initial potential energy

= 9,000 J

Power = Work/Time

=> Power = 9000/25

=> Power = 360 J/s

or 360 watt.

jek_recluse [69]

Answer:

64 softballs

Step-by-step explanation:

Coach Beard currently already has 24 softballs.

When she orders 2 more buckets with 20 in each, that's another 20 + 20 = 40 softballs added to the original 24. So, let's add these two numbers:

24 + 40 = 64

The answer is 64 softballs.

What is the surface area of a cone with a diameter of 28 cm. and height 22 cm in terms of Ï.
Svetlanka [38]

To find the surface area of a cone, use this formula.

pi (r) (r + [square root of h^2 plus r^2] )        substitute


h = height = 22                  r = radius = 28/2 = 14      [ ] = sq. root


pi (14) (14 + [ 22^2 + 14^2 ])                        solve exponents

pi (14) (14 + [484 + 196])                             add

pi (14) (14 + [680])                                       solve square root

pi (14) (14 + 2[170])                                     add

pi (14) (40.0768)                                         multiply

pi (561.075)  is about 561.1 rounded to nearest tenth


So the answer is C. 561.1pi cm^2
