Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. A feather and brick dropped together. Air resistance causes the feather to fall more slowly.

Hope it will help you ^_^
Explanation:
Answer: 5.8kg
Explanation:
F - mg sinΦ = ma
Given that
M=?
g= 9.8
Φ= 30
a= 2
F= 40 then
40 - 9.8 * m * sin 30 = 2 * m
40 = 2 * m + 9.8 * m * sin 30
40 = (2 + 9.8 * sin 30) m
m = 40 / (2 + 9.8 * 0.5)
m = 40 / (2 + 4.9)
m = 40 / 6.9
m = 5.797kg
m = 5.8kg
So here in order to find the average velocity we can say
so first we know that along the horizontal and along the inclined it moves with same time interval
so here we will have displacement in x direction as
now the average velocity in x direction will be given as
now similarly for y direction
first we will find its displacement
now the average velocity in y direction will be given as
now net velocity is given as
