3.92N
Explanation:
Given mass:
Mass of bag = 400g
The mass of a substance is the amount of matter it contains.
Weight of a substance is the vertical force acting on a body in the presence of gravity.
Weight = mass x gravity
Since the mass of the bag is 400g;
Now we convert to kg
1000g = 1kg
400g = = 0.4kg
Weight of bag = 0.4kg x 9.8m/s²
Weight of bag = 3.92N

Answer:
R = 0.0503 m
Explanation:
This is a projectile launching exercise, to find the range we can use the equation
R = v₀² sin 2θ / g
How we know the maximum height
² =
² - 2 g y
= 0
= √ 2 g y
= √ 2 9.8 / 15
= 1.14 m / s
Let's use trigonometry to find the speed
sin θ = / vo
vo = / sin θ
vo = 1.14 / sin 60
vo = 1.32 m / s
We calculate the range with the first equation
R = 1.32² sin(2 60) / 30
R = 0.0503 m
