Using the equation of motion v = u + at. v-the final velocity, u - initial velocity a- acceleration and t-the time.
increasing speed
If you know the Force (in Newtons) being applied on it, and its mass (in kg) you can use the equation- a=F/m.orIf you know the final speed (in meters per second), the initial speed and the time (in seconds), use the equation a=[final minus initial]/time.
87.5mi/hr2
Speed = (distance traveled) divided by (time to cover the distance) Speed = (50 meters) / (2 seconds) Speed = 50 meters per 2 seconds Speed = 25 meters per second
25mph
There is a formula to calculate the speed of a car after accelerating for four seconds. This formula is v = u + at, where v = velocity, u = initial velocity, a = acceleration, and t = the time it takes to accelerate.
60 m/s
There is sufficient information to determine Jack's speed at t equals 10 seconds.
No instantaneous speed is not final speed.
Not enough information. You also need to know how much the acceleration is. Once you know that, calculate the final speed, then calculate the average speed as (initial speed + final speed) / 2, and multiply that by the time to get the distance.
-- Your speed after 30 seconds will be 30 meters per second.-- Since your acceleration is constant, your average speed during the 30 secondsis the average of your initial and final speed . . . 15 meters per second.-- The distance you cover is your average speed for 30 seconds = 15 x 30 = 450 meters.
Speed can't be measured in seconds.
