Answer:
152,155 J
Explanation:
115,333 + 36,822 = 152,155J
Answer:
Total momentum = 50kgm/s
Explanation:
<u>Given the following data;</u>
Mass, M1 = 5kg
Mass, M2 = 7kg
Velocity, V1 = 10m/s
Velocity, V2 = 0m/s (since it's at rest).
To find the total momentum;
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
The law of conservation of momentum states that the total linear momentum of any closed system would always remain constant with respect to time.
Total momentum = M1V1 + M2V2
Substituting into the equation, we have;
Total momentum = 5*10 + 7*0
Total momentum = 50 + 0
<em>Total momentum = 50 kgm/s</em>
<em>Therefore, the total momentum of the bowling ball and the putty after they collide is 50 kgm/s. </em>
Answer:
Distance will decrease and work will decrease:
F = m a Newton's Second Law
a = F / m decreasing force will decrease acceleration
S = 1/2 a t^2 = 1/2 (F / m) t^2 distance traveled will decrease as force decreases
W = F * S work will decrease as both force and distance decrease
G=?
m=7.35*10^22kg
r=1.74*10^6m
G=6.67*10^-11nm^2kg^-2
you can use the formula
g=Gm/r^2
Wave speed = (wavelength) x (frequency)
= (4 m) x (2 /sec)
= 8 m/sec
