Answer:
a
Explanation:
because it is balanced and it is 40
Answer:
497.6 N
Explanation:
From the question,
The net force on the skydiver = weight of the skydiver- the resistive force of air
F' = W-F...................... Equation 1
Where W = weight of the skydiver, F = resistive force of air.
But,
W = mg................ Equation 2
Where m = mass of the skydiver, g = acceleration due to gravity.
Substitute equation 2 into equation 1
F' = mg-F............ Equation 3
Given: m = 87 kg, F = 355 N, g = 9.8 m/s²
Substitute these values into equation 3
F' = 87(9.8)-355
F' = 852.6-355
F' = 487.6 N
The potato reach a velocity of 0 m/s after 3.57 s
Explanation:
There is only one force acting on the potato, which is in free fall: the force of gravity, acting downward. Therefore, the motion of the potato is a free fall motion with constant acceleration equal to the acceleration of gravity, and we can use the suvat equation:
where
v is the final velocity
u is the initial velocity
is the acceleration of gravity (negative since downward)
t is the time
For the potato in this problem:
u = +35 m/s
So the time t at which the velocity reaches
v = 0
is
