Answer:
B. 0.50 meters/second^2
Explanation:
Given:
- mass of table (m) = 10.0 kg
- Eli's force (F1) = 120 N
- Andy's force (F2) = -125 N
Arranging Formulas and Substituting Values, Part 1:
- F = F1 + F2
- F = 120 + (-125)
- F = -5 N
- The -5 means that the table will move along the direction of the force applied by Andy.
Arranging Formulas and Substituting Values, Part 2:
- m * a = F
- a = F / M
- a = -5 / 10.0 kg
- a = -0.5 m/s^2
Answer:
solved
Explanation:
From the FBD in the attachment we can write that
N+ 80 sin37°= mg
N= 46×g-80×sin37=498.94 N
also, ma= 80×cos37°
a= 80×cos37°/46= 1.3889 m/s^2
also, 10m = 0.5at^2
put a= 1.3889 m/s^2
t= 2.095 secs
d) the speed v =at
v= 1.3889*2.095= 2.91 m/s^2
A). The sun is highest in London, but will not pass the ship
for another 5 hours.
Since the sun moves from east to west, the ship must be
5 hours west of Greenwich.
Each hour of sun motion is 15° of longitude.
The ship's longitude is (5 x 15°) = 75° West.
The ship may be sailing down Columbia Boulevard
in Maple Shade, New Jersey.
B). The latitude at Buffalo's City Hall is 42.887° North.
Polaris is always within about 2/3 of a degree of that angle
above the northern horizon, when viewed from City Hall.
Choice 2) is the most appropriate.
2 meters per second for 10 seconds is speed(2) multiplied by time(10)which is equal to 20meters
