Yo sup??
we can solve this problem by applying Newton's 2nd law
F*t=Δp
p=momentum
pi=mu=1500*30
pf=mv=m*0=0
Therefore
F*3=1500*30
F=15000 N
Hope this helps.
Such ions are said to be isoelectronic
Answer:
0.91m/s due west
Explanation:
Given parameters:
Time taken = 17.2s
Displacement = 15.6m
Unknown:
Velocity of the cart = ?
Solution:
Velocity of a body is the the displacement divided by the time taken.
Velocity =
Now insert the parameters and solve;
Velocity =
= 0.91m/s due west
