Answer:
a. 3.0 m/s^2
b. 18N
Explanation:
force = mass times acceleration
a.
box 1
24 = 2 times acceleration
24 divided by 2 = acceleration
acceleration = 24 divided by 2
acceleration = 12
box 2
24 = 6 times acceleration
24 divided by 2 = acceleration
acceleration = 24 divided by 6
acceleration = 4
acceleration is averaged
(2+4)/2 = 3

b.
its saying
in f = ma
if you have the same m of 6
and the a of 3
what is the force?
6 times 3 = 18
18 N
Answer:
Distance, d = 778.05 m
Explanation:
Given that,
Force acting on the car, F = 981 N
Mass of the car, m = 1550 kg
Initial speed of the car, v = 25 mi/h = 11.17 m/s
We need to find the distance covered by car if the force continues to be applied to the car. Firstly, lets find the acceleration of the car:
Let d is the distance covered by car. Using second equation of motion as :
So, the car will cover a distance of 778.05 meters.
Answer:
Speed does the 60-kg skater acquire relative to the ice = 0.281 m/s
Explanation:
Momentum is conserved in this case.
Initial momentum = Final momentum.
Initial momentum = Initial momentum of skater 1 + Initial momentum of skater 2
Initial momentum = 45 x 0 + 60 x 0 = 0 kg m/s
Final momentum = 45 x 0.375 + 60 x u = 16.875 + 60 u
Here we need to find u.
We have
0 = 16.875 + 60 u
u = -0.281 m/s
Speed does the 60-kg skater acquire relative to the ice = 0.281 m/s
Answer:
Protons, Neutrons, and electrons
Explanation:
Protons, electrons and neutrons are subatomic particles
Protons is positively charged particle yan
The electrons a negatively cacricated particle
Neutrons are particles that have no charge
