vt = velocity at time t
v0 = initial velocity
a = acceleration
t = time
vt = v0 + a * t
vt = 1000 + 4 * 100
vt = 1400 m/s
6 meters per second. Explanation: After 1 second = 2 meters per second. After 2 seconds = 4 meters per second. After 3 seconds = 6 meters per second.
If the acceleration was constant (15 + 25) /2 = 20 (time does not figure into the averaging at all!)
Average acceleration = (change in speed) / (time for the change) = (88 - 44) / (11) = 4 meters per second2
IF it started out from rest, then V = a t = (7.8 x 30) = 234 meters per secondin the direction of the acceleration, at the end of 30 seconds.
At the end of 7.508 seconds, the car has traveled 62 meters, and it's speed is 16.517 meters per second.
60.912 meters in that time
That's easy, if the car is initially traveling at 25 meters per second and gradually accelerates 3 meters per second for 6 seconds then the car is traveling at 43 meters per second.
6 meters per second. Explanation: After 1 second = 2 meters per second. After 2 seconds = 4 meters per second. After 3 seconds = 6 meters per second.
The acceleration of the body is 3 m/sΒ²
3 m/s2
Velocity is a vector quantity that includes both speed and direction. To calculate the velocity of Rob on a skateboard, we need to know the distance he traveled in meters and the direction of his motion. If Rob travels 10 meters in 3 seconds, the velocity would be 10 meters/3 seconds = 3.33 m/s (assuming no change in direction).
If the acceleration was constant (15 + 25) /2 = 20 (time does not figure into the averaging at all!)
Sound travels at a speed of approximately 1,500 meters per second in water. Therefore, in 4 seconds, sound would travel approximately 6,000 meters through water.
Average acceleration = (change in speed) / (time for the change) = (88 - 44) / (11) = 4 meters per second2
IF it started out from rest, then V = a t = (7.8 x 30) = 234 meters per secondin the direction of the acceleration, at the end of 30 seconds.
At the end of 7.508 seconds, the car has traveled 62 meters, and it's speed is 16.517 meters per second.
50 meters in 10 seconds is faster. you go 5 meters per second in 50 meters per second, and you go 6 meters a second in 5 seconds..
