The work done on the sail is 600 J
Explanation:
The work done to lift the sail is equal to the gain in gravitational potential energy of the sail, therefore is:
where
m is the mass of the sail
g is the acceleration of gravity
(mg) is the weight of the sail
is the change in height of the sail
In this problem we have
mg = 150 N (weight)
Substituting, we find the work done:

Answer:
its deepend on where you stand but. most cases g = 10 m/s²
W = M X G
W = 13 kg x 10 m/s²
W = 130 N

option b is correct brainlist ke
Answer: Frequency distribution helps to understand data. some complex data needs to be converted into intervals to see its frequency of occurrence. it helps to find the mean median and mode of the data. It helps in the analysis of data and its practical implementation.
Explanation:
Answer:
The answer to question is below
Explanation:
Data
t1 = 0
vo = 4 m/s
a)
d = vot + 
d = 4t + 
b)
c)
= 
t² = 32
t = 5.66 s
d)
d = 4(5.66) + 0.75(5.66)²
d = 22.64 + 24.02
d = 46.67 m
