Please give me correct answer my exam questions is this ...​

Answer 1

Answer:

Given :-

m =200 kg

h = 9 m

t = 2min = 2× 60 = 120s

To find:-

Power

Solution :-

Acceleration due to gravity, g = 10 m/s

Therefore, using the formula,

{\underline{\boxed{P = \sf\frac{Work \: done}{time \: taken}}}}

P=

timetaken

\sf \longrightarrow \: \frac{200 \times 10 \times 9}{120}⟶

120
