Exothermic is the answer to your question
Answer:
7.644 feet
Explanation:
Free fall means that an object is falling freely with no forces acting upon it except gravity, a defined constant, g = -9.8 m/s2. The distance the object falls, or height, h, is 1/2 gravity x the square of the time falling.
Explanation:
a. The net force is the upward force of the chute minus the weight of the crate.
∑F = F − mg
∑F = 150 N − (11 kg) (9.8 m/s²)
∑F = 42.2 N
b. From Newton's second law, the net force equals the mass times acceleration:
∑F = ma
42.2 N = (11 kg) a
a = 3.84 m/s²
c. Acceleration is the change in velocity over change in time. Assuming the crate is released from rest:
v = at + v₀
v = (3.84 m/s²) (5 s) + (0 m/s)
v = 19.2 m/s
