Answer:
12/13 kg, 18/13 kg
Explanation:
Let the masses are m and m'.
acceleration, a = 3.2 m/s^2
Force, F = 30 N
Tension, T = 18 N
By the diagram, using Newton's second law
F - T - m'g = m' a .... (1)
T - mg = ma ..... (2)
Substitute the values of F, T and a in equation (1) and equation (2)
30 - 18 = m' (9.8 + 3.2)
12 = 13 m'
m' = 12/ 13 kg
And, 18 = m (9.8 + 3.2)
m = 18/13 kg
Answer:
It's called the working distance
.
Answer:
5900J
Explanation:
Work=Forse*Distance
work = J, Jewls
100*59=5900
Hop this helps and can u think about brainlist
i put a picture on how to find these answers, if u got any more questions im here
Increase because the mass of an object aligns with its weight
Horizontal component = V cos(30°) = V (√3/2) = 73.2 m/s
Vertical component = V sin(30°) = V (0.5) = 100 m/s
In 6 seconds, the object travels horizontally (173.2 m/s x 6 sec) = 1,039 m
After 6 seconds, the object's height above the ground is
H = V₀t + 1/2 a t²
H = (100 m/s)(6 s) + (1/2) (-9.8 m/s²) (6 s)²
H = (600 m) - (4.9 m/s²) (36 s²)
H = (600 m) - (176.4 m)
Height = 423.6 m
