Answer:
number 10 is the value of acceleration due to gravity.
A) an object with mass > 0 in a gravitational field
b) an object with an electric charge not 0 in an electric field
c) a moving object with an electric charge not 0 in a magnetic field
Answer:
13 m in the + x direction.
Explanation:
Givens
m1 = m
m2 = 3m
v1= ? = x
v2 = - 3 m/s
v3 = v4 = - 1 m/s
Equation
Let x be the speed of the lighter object before collision.
Momentum before collision = momentum after collision
Solution
mx - 3m * 3m/s = (m1 + m2)*(-1)
m(x - 3*3m/s) = (m + 3m)(-1)
m(x - 9) = - 4m Cancel the ms
x - 9 = 4 Add 9 to both sides
x = 9 + 4
x = 13 m/s
It would be false as your answer
Answer:
22) 5.6 Kg.m/s
23) 0.067 Kg
24) 1.16 m/s
Explanation:
Momentum is found by multiplying mass and velocity
P=mv where P is momentum, m is mass of object and v is the velocity
22
Given
Mass, m=2 Kg
Rate, v=2.8 m/s
Relationship
P=mv
Solution
P=mv=2*2.8=5.6 Kg.m/s
23
Given
Momentum, p=0.1 Kg.m/s
Rate, v=1.5 m/s
Relationship
P=mv and making m the subject then
Solution
24
Given
Momentum,
Mass,
Relationship
P=mv and making v the subject then
