The answer is that it is an elastic collision.
<u>Explanation:</u>
When two objects come in direct contact with each other, the collision occurs. It is the event in which two or more bodies exert forces on each other in about a relatively short time.
As a result of a collision, No losses in the kinetic energy.
The formula for an elastic collision of momentum is given by
m1u1 +m2u2 = m1v1 + m2v2
where m1,m2 represents the mass of 1st and 2nd body
u1, u2 represents the initial velocity of the first and second body
v1, v2 represents the final velocity of the first and second bodies.
During a collision, the kinetic energy before the collision will be equal to the kinetic energy after the collision.
Smaller the force, greater the collision acting upon the object.
It is easier to start a fitness program then to maintain one because D. all of the above
I am gonna guess
1) 8m
2) total time
3) instantaneous acceleration
4) the train’s acceleration is negative
5) equal zero
6) acceleration due to gravity
Answer:
<h2>
38,769.23 miles</h2>
Explanation:
given:
A car is traveling at an average speed of 70 m/s.
find:
How many km would the car travel in 6.5 hrs. ?
solution:
distance = velocity over time
let velocity = 70 m/s
time = 6.5 hrs.
convert velocity 70 m/s into m/h for consistency of units.
<u>70 mi. </u> x <u>3600 sec.</u> = 252,000 mi/hour
sec. 1 hr.
now plugin values into the formula d = v/t
d = <u>252,000 miles/hour </u>
6.5 hours
d = 38,769.23 miles
therefore, the distance travelled in 6.5 hours with a speed of 70 m/s is 38,769.23 miles
