A = <0,1>
B = <-1,3>
then
A + B = < 0+-1 , 1+3 > = <-1, 4>
magnitude = sqrt( (-1)^2 + (4)^2 )
= sqrt( 1 + 16)
= sqrt(17)
Answer:
The 7.0-kg bowling ball with a speed of 6.0 meters per second
Explanation:
Momentum is p=mv
m = mass, v = velocity. (velocity is speed with direction)
1. 0.046-kg golf ball with a speed of 60.0 meters per second.
The mass is 0.046kg , velocty is 60.0
p= mv = 0.046 x 60 = 2.76kg
2. 7.0-kg bowling ball with a speed of 6.0 meters per second
Mass is 7kg, velocity = 6
p=mv = 7 x 6 = 42kg
The 7.0kg bowling ball has more momentum because 42 is greater than 2.76.
Is where scientist easily handle very small numbers or very large numbers. It best that way.
Answer:
Mechanical advantage
Explanation:
Machines help us in giving more output than the input incurred so it only increases mechanical advantage, all the other quantities are dependent on the mechanical advantage.
