Answer:
The velocity of wind with respect to cyclist is 
.
Explanation:
speed of cyclist = 12 km/h east
speed of wind = 5 km/h south west
Write the speeds in the vector form
The velocity of wind with respect to cyclist is
Given: Please see the attached image below.
To be able to
subtract vectors, we can either use the parallelogram method or the triangle
method. Take note that the only difference is that alternatively adding vectors
A and B, we will instead be adding A and – B. When we ponder of vector subtraction, we must
anticipate about it in terms of adding a negative vector. A negative vector has the same magnitude as the
original vector, however, it has an opposite direction.
So in this problem, the two vectors that will have the
largest magnitude are A & F when subtracted (i.e., when one vector is
subtracted from the other).
Answer:
The answer to your question is: F = 924 N
Explanation:
Data
v = 28 m/s
m = 66 kg
d = 56 cm
F = ?
Formula
v = d/t
a = v/t
F = ma
Process
t = d/v = 56 / 28 = 2 s
a = v/t = 28 / 2 = 14 m/s²
F = 66 (14) = 924 N
