Answer:
3.82 Ns
Explanation:
Time varying horizontal Force is given as
F(t) = A t⁴ + B t²
F(t) = 4.50 t⁴ + 8.75 t²
Impulse imparted is given as





Answer:
D
Explanation:
speed = frequency x wavelength
speed of light in vacuum is 3.0 x 10^8
wavelength = 5.32 x10 ^-7
3.0 x 10 ^ 8 = 5.32 x 10^-7 x frequency
frequency = 5.63909 x 10^14
round it off = 5.64 x 10^14 Hz
thus the answer is D

Answer:
3.192 m/s
Explanation:
t = Time taken = 0.900 seconds
u = Initial velocity
v = Final velocity
s = Displacement = 1.1 meters
a = Acceleration due to gravity = 9.81 m/s²

Velocity of the elevator when it snapped is 3.192 m/s
As an object falls from rest, its gravitational energy is converted to kinetic energy
G.P.E = K.E = mgh
K.E = (80 Kg)(9.8 m/s²)(30 m)
K.E. = 23,520 J

Explanation:
In a weightless environment a force of 5 Newtons is applied horizontally to the right on a rock with a mass of 1 kg and to a pebble with a mass of 0.1 kg.
