<span>Distance in Miles (.25) x 3600 (seconds in an hour) / time in seconds = 200 MPH. Drag racing calculates the top speed via a speed trap starting 66 feet from the finish line.</span>
Answer:
Acceleration= 1,59 (meters/(second^2))
Direction= NE; 65,22° above the east direction.
Explanation:
Resulting force= ( ((180N)^2) + ((390N)^2) ) ^ (1/2) = 429,53 N
Angle obove the east direction= ((cos) ^ (-1)) (180N / 429,53 N) = 65,22°
Acceleration= Resulting force / mass = (429,53 N) / (270 kg) =
= (429,53 kg × (meters/(second^2))) / (270kg) = 1,59 (meters/(second^2))
Answer:
Boron 11
Explanation:
This element is Boron because it has 5 protons.
The isotope is Boron - 11 because it has 5 protons and 6 neutrons, 6+5=11.
Answer:
Please find the answer in the explanation
Explanation:
Constant velocity is the uniform velocity. That is, the velocity is steady and it does not change. You will have a constant velocity when you maintain a certain velocity for a long time without changing it.
At constant velocity, acceleration is equal to zero.
Instantaneous velocity is the change in distance in a specific direction per specific time. It is a velocity at a certain time. It is not uniform.
Change in instantaneous velocity is equal to acceleration.
Answer:
8 seconds
Explanation:
Answer:
Explanation:
Going up
Time taken to reach maximum height= usin∅/g
=3 secs
Maximum height= H+[(usin∅)²/2g]
=80+[(60sin30)²/20]
=125 meters
Coming Down
Maximum height= ½gt²
125= ½(10)(t²)
t=5 secs
