72 km/h.
60 min per hr x 60 sec per min. 3600 / 5 sec. equals 720 x 100 (distance cover in 5 sec) = 72000M per hr / 1000 meter in 1 kilometer. = 72km/h.
The velocity of the object is 10 m/s.
10.9 m/s
The minimum velocity of the missile would depend on the time it takes for the missile to reach the target. If the missile travels 100 meters in 1 second, then the minimum velocity would be 100 m/s.
A car traveling at 10m/s, or 36km/h.
Half a second every metre.
3.61 meters
velocity=5 meters/sec Velocity=change in distance/change in time velocity=m/s change in distance=meters change in time=sec v=x/t v=100m/20s v=5m/s
An example problem involving speed is calculating the average speed of a car that travels 100 miles in 2 hours. An example problem involving velocity is determining the velocity of a ball thrown upward with an initial velocity of 20 m/s at a height of 40 meters above the ground.
(100,000 meters/hour) x (0.13 second) / (3,600 seconds / hour) = 3.6111 meters (rounded, repeating)
speed = distance / time 100 m / 25 sec = 4 m/sec
0.1 x 3600/5 = 72 kph
Speed = distance/time So speed = 100/5 = 20 Answer: 20m/s.
