solve the following problem
(c) Calculate the work done in taking an
object of mass 15 kg to a height of 10 m. (g = 9.8 m/s2)
Ans.​

Answer 1

Answer:

as we know know the formula of work done for height is MGH where m stands for mass in KG g stands for gravity of earth and stands for height in metre metre.

simply we multiply all the given terms and we got the answer.

15 x 9.8 x 10 = 1470 juul

Answer 2

$\huge\underline{\overline{\mid{\bold{\red{ANSWER-}}\mid}}}$

1470J

Explanation:

we know the formula of force that is F= ma here a = acceleration of gravity that is 9.8 m/s²

F = m × g

F= 15 × 9.8

F= 147N

we know, work done [W]

W= force × displacement

W= 147 × 10

$\boxed{W= 1470 J}$
