Answer 1

$\sf{\underline{\huge{\rm{Solution:}}}}$

Given,

• F = 7 N
• s = 1.5 m

We known that,

$\sf{Work = Force × Distance}$

$\:\:\:\:\:\:\:\:\:\:\sf{= 7 N × 1.5 m}$

$\:\:\:\:\:\:\:\:\:\:\sf{= 10.5 J}$

Answer 2

$\huge{\red{\boxed{\blue{\boxed{\pink{Answer}}}}}}$

➡️✨✨Work = Mass x Gravity x Height. the mass of the luggage is =15 kg

the constant of gravity is= 10 m/s^2

the height is = 1.5 m

Therefore, the total amount of work done can be calculated by multiplying these three values, that is, Work:-

15 x 10 x 1.5 = 225 Joules.✨✨
