newton/kilogram is the answer.please mark me brainliest
Answer:
5.90 ft/s^2
Explanation:
There are mixed units in this question....convert everything to miles or feet
and hr to s
28 mi / hr = 41.066 ft/s
Displacement = vo t + 1/2 at^2
599 = 41.066 (8.9) + 1/2 a (8.9^2)
solve for a = ~ 5.90 ft/s^2
Answer:
T = 0.00889 N*m
Explanation:
Given the initial speed
Vo = 9.0rev/s.
V = 65 rev/10s
V = 6.5 rev/s.
V = Vo + a*t
Solve to acceleration knowing the initial velocity and the velocity at 10 s
6.5 rev/s - 9 rev/s = a*10s
a = -0.25 rev/s^2.
Now the solve the time at stop time so V=0
V = Vo + a*t
0 = 9.0 - 0.25 rev/s *t,
t = 36 s The Stopping time.
36s - 10s = 26s
The torque can be find using the acceleration using the equation
T = I*a
I = 1/2*m*r^2
I = 1/2*0.725kg*(0.315m)^2= 0.0359kg*m^2
T = 0.0359kg*m^2*-0.25rev/s^2
T = 0.00889 N*m
Answer:
The Nucleus
Explanation:
The nucleus contains the majority of an atom's mass because protons and neutrons are much heavier than electrons, whereas electrons occupy almost all of an atom's volume. I hope this helps you :D
Answer: (a) 5Joules
(b) 10m/s
(c) 1.0kgm/s
(d) 33.3N
Explanation:
(a) P E = mass * gravity * height
= 0.1*10*5 = 5Joules
(b) All PE is converted to KE
Therefore;
KE = 1/2 * mass * velocity^2
5 = 1/2 * 0.1 * v^2
V = sqrt(100)
v = 10m/s
(c) change in momentum = mass * velocity
= 0.1 * 10
= 1.0kgm/s
(d) impulse = change in momentum
Change in momentum = force * time
1.0 = force * 0.03
Force = 1.0/0.03
Force = 33.3N
Therefore, the force acting on the egg is 33.3N
