10 x 4^2 = 160 / 8..
V = 20m/s...
...x 8 = 100 miles,meters, metric what ever m stands for after 8 seconds.
This is my guess since the problem says 4m/s^2
V= distance/ ST (traveled/used)
Answer & Explanation:
volume of the block = 4.5 x 5 x 6 = 135 cm^3 also equal to 1.35 x 10^-4 m^3
USE THE FORMULA
<em>Density = mass / volume</em>
<em><u /></em>
<em><u>Answer in gcm^-3</u></em>
<em>Density = 1502 / 135</em>
<u>Density = 11.1 gcm^-3</u>
<em><u /></em>
<em><u>Answer in kgm^-3</u></em>
<em>Density = 1.502 / 1.35 x 10^-4</em>
<u>Density = 11125.9 kgm^-3</u>
Answer:
8 m
Explanation:
Vertical component of the speed of the boat = 3.0 m/s
horizontal component of the boat = 4 m/s
the rowboat traveled the length of the river which = 6.0 m
time taken to travel across the 6 m wide river = 6 m / 3 m/s = 2 s
the distance far downstream of the starting point = horizontal speed × time = 4 m/s × 2 = 8 m
The acceleration is 1.67 m/s²
<u>Explanation:</u>
Given:
Speed, s = 60km/hr
s = m/s
s = 16.67 m/s
Time, t = 10 seconds
Acceleration, a = ?
We know:
On substituting the value, we get:
Therefore, the acceleration is 1.67 m/s²
I’m pretty sure one increases just straight up velocity and the other is kind of a deceleration
