Answer:
10.116 Pounds/45 newtons = 10.1164024 pounds/force
Explanation:
Divide the newtons by the rate of acceleration, which will give you the mass of the object. The mass will be in kilograms, because a single newton represents the amount of force needed to move one kilogram one meter. For our example, we will divide 10 N by 2 m/s/s, which give us a mass of 5 kg
Answer:
216.39 N/m
Explanation:
F = 64.7 N
x = 0.299 m
Plug those values into Hooke's Law:
F = kx
64.7 N = k(0.299 m)
---> k = 216.39 N/m
Her acceleration is
(250) divided by (the swimmer's mass, in kilograms).
The unit is " meters per second² " .
Speed = (frequency)•(wavelength)
Speed = (2 Hz)•(2.5 m)
Speed = 5 m/s (choice-D)
