a few things missing:
- How fast is the acceleration?
- How long does it take to go from 4ms to 20ms?

Average speed = (250 / 5) = 50 meters per second.Initial speed = 0Final speed = 100 m/sAcceleration = (100 / 5) = 20 m/s2===> Must be a rocket-propelled ball; its acceleration is 2G !
When a vehicle starts from rest, you may experience a slight jolt or movement as the engine engages and the vehicle begins to move forward. You may also hear the engine revving as it builds up power to propel the vehicle. Additionally, you may feel a gradual increase in speed as the vehicle accelerates.
the final velocity = initial velocity + acceleration x time; since acceleration is negative final velocity = 45 - 10x3 = 45 -30 = 15 mph
Initial speed = 0Final speed = (2.6 x 6.4) = 16.64 m/sAverage speed = 8.32 m/sDistance = (average speed) x (time) = (8.32 x 8.4) = 53.248 meters
F=m.a The weight of the plane for all intents and purposes remains constant. Since you're already given the average acceleration, that is a constant as well. Therefore the average force is the product of the two. Regardless of the other data. You can do the maths.

60.912 meters in that time
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.
Question:A car starts from rest and accelerates uniformly. It acquires a velocity of 72 km/hr in 10 seconds. What is its acceleration?Answer:Since the car is starting fom rest, its initial velcity (u) = 0Final velocity (v) = 72 km/hr =20 m/sTime taken for change of velocity (t) = 10 secondsAcceleration, a = (v-u)/t = (20-0)/10 = 20/10 = 2 m/s2
the final velocity = initial velocity + acceleration x time; since acceleration is negative final velocity = 45 - 10x3 = 45 -30 = 15 mph
Fishing tends to start out slow, then accelerates quickly through the month of August.
A race car has a mass of 708 kg It starts from rest and travels 35 m in 3.2 s The car is uniformly accelerated during the entire time What net force is applied to it? . Total distance moved = Vi * t + ½ * at^2 It starts from rest Initial velocity = 0 . And travels 35 m Distance = 35 m . in 3.2 s time = 3.2 s . Total distance moved = Vi * t + ½ * at^2 35 = 0 + ½ * a *3.2^2 35 = ½ * a * 10.24 . a = (35 * 2) ÷ 10.24 a = 6.836 m/s^2 . Force = mass * acceleration Mass = 708 kg . Force = 708 * 6.836= Force = 4839.9 N .

Q.Your car starts then seconds later it shut off what wrong A. that must be some crappy car
Your 1991 4.3 S10 starts for about 3 seconds then shuts down because it is faulty. Take it to mechanic to have it checked.
Unknown: final velocity, vfKnown:initial velocity, vi = 0m/stime, t = 15.0saverage acceleration, a = 2.40m/s2Equation:vf = vi + atSolution:vf = 0 + 2.40m/s2 x 15.0s = 36.0m/s
