Mass of the boxcar = M = 200 (1000 kg ) = 2*105 kg
inclination = θ= 2.5o
acceleration = a= g sin θ = (9.8) sin 2.5o = 0.427 m/s2
during the time = t = 10 sec
initial velocity = U = 0 m/s
final velocity = V = ?
a = V - U / t
V = at = (0.427)(10) = 4.27 m/s
considered speed= ? considered distance= 309 meters considered time= 17 seconds therefore speed= 309/17 = 18.7 meters per second = 1122 kilometers per hour
There are 60 minutes in an hour. Thus to convert from hours to minutes you need to multiply by 60. In this case we have one hour so that becomes 60, add the 3 given in the question and we have 63 minutes. The next step is to multiply this by 60 to convert into seconds. 63 x 60 = 3780. Add this on to the five seconds given in the question and we have a final answer of 3,785.
Yes, completing 100 meters in 13 seconds is considered a good time, especially for amateur runners or those participating in local competitions. For context, elite male sprinters typically run this distance in under 10 seconds, while elite female sprinters can achieve it in around 11 seconds. A time of 13 seconds indicates a solid level of speed and fitness for recreational athletes.
If your time was 15 seconds in a race, it is most likely that you ran the 100-meter sprint. The 100-meter sprint is a common track and field event that tests speed and acceleration over a short distance. A time of 15 seconds would be considered a good time for an amateur runner, but elite sprinters can complete the race in under 10 seconds.
Ninety seconds is equal to one minute and thirty seconds. It represents a short duration of time, often used in various contexts such as timing events or activities. In the larger context of time, it can be considered a brief interval, typically not long enough to accomplish significant tasks but useful for quick actions or decisions.

In older pediatric patients 2-4 seconds can be considered "normal," but factors such as respiratory status and ambient temperature need to be considered in relation to these times as well. In neonates, because capillaries of the head and/or chest are sometimes used for assessment, different values appear in the literature. An upper limit of 3 seconds is a general guideline, but averages of roughly 2 seconds are considered "normal."
No. Bouncing the ball is still considered possession, and the keeper is only allowed to possess the ball for 6 seconds.
A sophomore in high school should be able to run something in the low 15 sec range.
Is 10 - 20 seconds even considered sex?
When an object is dropped near the Earth's surface, and it experiences no air resistance, then its speed after 3 seconds is 29.4 meters (96.5 feet) per second, and its velocity is directed toward the Earth's center of mass, nominally the Earth's geometric center, colloquially referred to in the bourgoise vernacular as "down".
