3 hours, because for every 50 km equals one hour 150 divided into 50 equals 3
Answer:
a=1.8 m/s^2
Explanation:
F=ma
So
a=F/m
Where F=1800 N, m=1000 kg
a=1800/1000
a=1.8m/s^2
Answer:
The arrow-apple combo will move with a velocity 3.6 m/s to the right.
Explanation:
Use the law of conservation of momentum to solve this problem. In this case the law can be written as follows:
from which the desired velocity can be isolated:
The arrow-apple combo will move with a velocity 3.6 m/s to the right.
Answer:
Explanation:
Given that,
Initial force,
distance, d = 2 m
New distance, d' = 4 m
We need to find the new force. The electrostatic force between two charges is given by :
So,
So, the new force is equal to .
