If a train is accelerating at a rate of 4km per hour per second and its initial velocity is 20km per hour what is its velocity after 30 seconds?
The train's velocity after 30 seconds can be calculated using the formula: final velocity = initial velocity + (acceleration * time). Plugging in the values, final velocity = 20 km/hr + (4 km/hr/s * 30 s) = 20 km/hr + 120 km/hr = 140 km/hr. So, the train's velocity after 30 seconds is 140 km/hr.

How far does a plane fly in 15 seconds while its velocity is increasing from 75 miles per second to 145 miles per second at a uniform rate of acceleration?
To find the distance traveled, we can use the formula: distance = initial velocity * time + 0.5 * acceleration * time^2. The initial velocity is 75 miles per second, the final velocity is 145 miles per second, and the time is 15 seconds. The acceleration can be found using the formula: acceleration = (final velocity - initial velocity) / time. Plug in the values to find the acceleration and then calculate the distance traveled in 15 seconds.
Find the acceleration of a car that goes from A meters per second to B meters per second in 8 seconds?
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Given the initial velocity (A), final velocity (B), and time (8 seconds), you can substitute the values into the formula to find the acceleration.
What is the velocity of the ball 0.6 seconds after its release?
Assuming you release it from a position of rest, you must multiply the time by the acceleration. The acceleration due to gravity near Earth's surface is approximately 9.8 meters/second squared.
What does it mean for an object to accelerate at 10 mss use an examble?
Acceleration is the rate at the speed or velocity of a body increases per unit time. An object that accelerate at 10 mss means the rate at which it's velocity is changing per unit second is 10m/s. For instance, an object accelerating at 10 mss for 3 second will have a velocity of 30m/s.
A speed bike tops a hill at 3.50 ms an accelerates steadily down the hill until reaching a speed of 11.4 ms after 4.20 second how far did the bike travel durig this period?
You can find the distance traveled by the bike by using the formula: distance = initial velocity * time + 0.5 * acceleration * time^2. In this case, the initial velocity is 3.50 m/s, the final velocity is 11.4 m/s, the time is 4.20 seconds, and since the bike is accelerating, you can find the acceleration using the equation: acceleration = (final velocity - initial velocity) / time. Plug these values into the formula to find the distance traveled.

A sprinter explodes out of the starting block with an acceleration pf 2.3 ms2 which she sustains for 1.2 sThenher acceleration drops to zero for the rest of the raceWhat is her velocity at1.2s?
The sprinter's velocity at 1.2 seconds can be calculated using the formula: velocity = initial velocity + acceleration × time. Given the initial velocity is 0 m/s, acceleration is 2.3 m/s^2, and time is 1.2 seconds, the velocity at 1.2 seconds would be 2.76 m/s.

If a gun is fired straight upward and the bullet leaves the gun at 100ft per second after 2 seconds the velocity of the bullet is 36 feet per second what is the velocity after 3 seconds?
Since the bullet is fired straight upward, it will be decelerating due to gravity acting in the opposite direction of its initial velocity. Thus, at t = 3 seconds, the velocity will be less than 36ft per second but still positive (as it's moving upward). To calculate the exact velocity, you would need to use the kinematic equation for velocity in one dimension.
If an aircraft on its take-off run has a steady acceleration of 3 meters per second squared what velocity does the aircraft gain in 4 seconds?
The velocity gained by the aircraft in 4 seconds can be calculated using the formula: velocity = acceleration × time. Given acceleration of 3 m/s^2 and time of 4 seconds, the velocity gained by the aircraft would be 12 meters per second.
What is the velocity of an object accelerating at 3 meter per second per second with a force of 12N?
We can only give the mass of the object. Newton's second law of motion will show that Force = mass x acceleration. therefore 12 Newtons = 4 kilogrammes x 3 m/s2 To calculate final velocity you will need to specify the time, the acceleration (and the initial velocity).
