Answer:
Explanation:
The 2 equations we need for this are
and
d = rt. First we need to find the velocity using the first equation, then we will plug it into the distance equation as the rate to find the time.
v = 331.5 + .606(20.0) I used 3 sig figs for the temp instead of the 1 found in 20.
v = 331.5 + 12.1 so
v = 343.6 m/s
Now, before we can find the time in seconds, we need to convert the distance to meters.
1.75 km = 1750 m:
1750 = 343.6t so
t = 5.09 seconds
Answer:
Explanation:
given,
velocity of particle 1 = 0.741 c to left
velocity of second particle = 0.543 c to right
relative velocity between the particle = ?
for the relative velocity calculation we have formula
u_x = 0.543 c
v_x = - 0.741 c
Relative velocity of the particle is
Answer:
The torque about the origin is
Explanation:
Torque is the cross product between force
and vector position
respect a fixed point (in our case the origin):
There are multiple ways to calculate a cross product but we're going to use most common method, finding the determinant of the matrix:
