Answer:
a) a = 8m/s^2
b) a = 9.8m/s^2
c) a = 200m/s^2
d) a = 9.8m/s^2
Explanation:
Using the laws of newton:
F = ma
where F is the force, m the mass and a the aceleration
a) Solving for the aceleration:
a = F/m
so, replacing the force and the mass of Blanche, we get:
a = 800N/100kg
a = 8m/s^2
b) By the laws of newton, the sumatory of vertical force for Blanche is equal to:
mg = ma
Where g is the gravity
Then, solving for a:
a = g
a = 9.8m/s^2
c) At the same way, solving for the aceleration:
a = F/m
so, replacing the values of the force and the mass of the shot, we get:
a = 800N/4kg
a = 200m/s^2
d) Then, sumatory of vertical force for the shot is equal to:
mg = ma
where g is the gravity
solving for a:
a = g
a = 9.8m/s^2
The answer is C, A CD-ROM is a compact disk that contains stored
information that can be read on a computer. which can be used and store
for a long time. A CD-ROM store data in digital format. data is written
from a laser light on the disk. Minimum capacity this drive is around
700 MB.
The formula is a= chance in velocity/time
A=10-0/2
A=10/2
A=5 m/s^2 (meters per second squared)
