When the car comes to a stop, the final velocity must be 0 m/s.
Since the car js decelerating in a forward direction, acceleration must be negative.
final v = initial v + a•t
0 = 20 + (-6)t
t = 3.33s
B. trajectory
because it is a set projectile wether or not it was calculated
plz mark brainliest
The unit of pressure is the Pascal (Pa), equivalent to
.
In space, spatial coordinates can be roughly divided into measures of Right ascension and declination. The declination is measured in degrees while the ascent is measured in hours, minutes, seconds. When you have objects in space such as those of the characteristics presented we will have to they are not necessarily close together in the sky because we can find two stars on the same right ascension but on different declination lines (Which means they can be very far apart from each other)
Answer:
Explanation:
Six waves passes by under 60second interval
Since it has 6 waves,
Then, it correspond to 3 wavelength
Then,
The period of each Each wavelength is 60 / 3
Then, period = 20seconds
From the relationship between frequency and period
f = 1 / T
f = 1 / 20
f = 0.05 Hz
