Answer:
<h3>F = 35.84N</h3>
Explanation:
Force = mass * acceleration (Newton's second law of motion)
Given
Mass = 32kg
Get the acceleration using the expression d = 1/2at^2
3.5 = 1/2 (a)2.5^2
3.5 = 3.125a
a = 3.5/3.125
a = 1.12m/s^2
Get the net force;
F = 3.2 * 1.12
F = 35.84N
Hence the net force used to accelerate is 35.84N
Answer:
total distance is 11.3 miles
Explanation:
Given data:
distance to north = 1.2 miles
distance to south at 38 degree east of south = 6.1 miles
distance to east of north at angle 89 degree = 4 miles
distance to east of north at angle 31 degree = 6.5 miles
considering each displacement as vector so we have

total distance is

Explanation:
The wavelength of a wave is given by

where
v is the speed of the wave
f is the frequency of the wave
For the sonar signal in this problem,


Substituting into the equation, we find the wavelength:
