Momentum (p) is equal to the product of an object's mass (m) and its change in velocity (v).
Change in velocity (v) results in change in momentum (p), which is equal to impulse. Impulse (J) is also equal to an applied force (F) over a period of time (t).
Combining p=mv and J=F t together:
m (v final - v initial) = F t
(2,500 kg) (70 m/s - 30 m/s) = F (10 s)
Solving for F we get:
10,000 N of force
Answer:
$539.94
Step-by-step explanation:
The formula for calculating future value:
FV = P (1 + r/m)^mn
FV = Future value
P = Present value = $400
R = interest rate = 2.5/ 365
N = number of years = 12 x 365
$400 x ( 1 + 0.025/365)^4380 = $539.94
Answer:
x = 1, y = 1
Step-by-step explanation:
Use system of equations to solve for x and y by using substitution
√x + 11=15 x=16
√x= 15-11 x=16

0.28: 0.12 + 0.60 = 0.72. Probability is always out of 1, so 1 - 0.72 should give you the probability of losing, which is 0.28.
