Answer:
The faster an object moves, the more kinetic energy it has. The more mass an object has, the more kinetic energy it has.
Explanation:
Answer:
78.498N
Explanation:
The Net force provided by the spinnaker can be obtained from Newton's second law of motion as follows;
where m is the mass, v is the final velocity, u is the initial velocity and t is the time interval for which the force acted.
Given;
m =980lb
v = 12mi/h
u =8mi/hr
t = 10s.
It is important to convert all quantities to their SI units where necessary, so we do that as follows;
1lb = 0.45kg,
hence 980lb = 980 x 0.45kg = 441kg.
1mile = 1609.34m
1hour = 3600s,
therefore;
Substituting all values into equation (1), we obtain the following;
Answer:
The ratio of and is 0.9754
Explanation:
Given that,
Distance z = 4.50 d
First equation is
Second equation is
We need to calculate the ratio of and
Using formula
Put the value into the formula
Hence, The ratio of and is 0.9754
Answer:
1 cycle every 2 seconds if that is what it is asking. So you have to do 2 x 30 and you will get 60 so ur awnser is 60
