Formula of Convert from kmh to ms?
kmh to m/s formula n * 5/18 example: 100km/h convert to (n)m/s 100 * 5/18 = 27.7 m/s OR my way of doing this (much simpler): (km/h) / 3.6 = m/S example: (100km/h) / 3.6 = 27.8 m/s
If you run 50 meters in 10 seconds what is your speed?
1 hr = 3600 s 1000 m = 1 km speed = distance/time = 50m/10s = 5 m/s = 5 m/s x (3600 s/h) / (1000 m/km) = 18 km/h
How much work must be done on a 5-kg sled to increase its speed from 10 m/s to 15 m/s?
312.5 J
Which is faster 5 meters per second or 720 feet per minute?
5 m/s Convert to the same units, then a comparison can be made. 1 min = 60 seconds 1 ft = 0.3048 m (exactly) → 720 ft/min = 720 × 0.3048 m/min = 219.456 m/min 5 m/s = 5 × 60 m/60s = 300 m/min > 219.456 m/min → 5 m/s > 720 ft/min
What is the relation between speed-acceleration and time?
acceleration = the change in speed over time, assuming a linear motion. For example, the speed is 5 [m/s] at t = 0 and 100 [m/s] at t = 2 [min]. The average acceleration = (100 - 5) [m/s]/(2*60) [s] = 0.792 [m/s2]. When vectors are involved (a roller coaster ride or merry-go-round), the calculations will be a little more complicated, but the expression is very similar: A = (V2-V1)/(t2-t1), where A = the average acceleration vector; Vi = the velocity vector at time i. For the instantaneous acceleration, A = dV/dt. Please see the related link. =============================
