The acceleration of the ball can be easily found using the kinematic equation if = vi + at. Where vi = initial velocity, if = final velocity, a = acceleration, and t = seconds. The acceleration is -0.1 m/s^2.
Magnitude of acceleration = (change in speed)/(time for the change) = (-3)/(30) = -0.1m/s2 .
We can't say anything about the direction of acceleration, because there's no
information about the direction of the ball at any time during the observation.
To be honest about it, the question says "velocity" twice, but it only tells us
speed, not velocity.
-5 m/s, using the equation a = delta v over delta t to solve for acceleration.
a = 15 m/s - 25 m/s/2 = -5 m/s
-100 meters/second/second in the same direction of travel.
The reaction rate is 1.5x10^-2 M/s and I need to know at 10 seconds the amount of Cl2 gas. The balanced equation is 2 NO (g) + Cl2 (g) 2 NOCl (g). Please help
20 seconds
40 hours x 60 minutes per hour x 60 seconds per minute = 144,000 seconds. Final answer = 144,000 seconds in a 40 hour work week.
You divide by 1,000. So, 271 milliseconds equals 0.271 seconds.
1000 seconds.
That depends on its initial velocity and its acceleration. V1 = V0 + a * t
Acceleration occurs when velocity changes over time. The formula for it is as follows: a = (Vf - Vi) / t a: acceleration (meters/seconds2) Vf: Final velocity (meters/seconds) Vi: Initial Velocity (meters/seconds) t: Time (seconds)
Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
To calculate velocity using acceleration, start by multiplying the acceleration by the change in time. For example, if the acceleration is 10 m/s2 and the change in time is 5 seconds, then there is a 50 m/s increase in velocity. Then, add the initial velocity to the increase in velocity.
Acceleration = Change in Velocity / Change in Time a = (Final Velocity - Initial Velocity) / (Final Time - Initial Time) = (55-0)/(5-0) = 55/5 a = 11 m/s^2
the final velocity = initial velocity + acceleration x time; since acceleration is negative final velocity = 45 - 10x3 = 45 -30 = 15 mph
You need more details.The final velocity could be 0However, you need to know the initial velocity, and the braking acceleration, and perhaps other acceleration/deceleration factors to know the true answer.
It will depend upon the initial velocity of the body. If 'u' be the initial velocity of the body, then the final velocity will be: v = u + at (v = final velocity, a = acceleration, t = time) i.e., v=u+10*7 = (u + 70) m/sec. If u=0 (i.e the initial velocity be zero) then final velocity, v=70 m/sec.
I'm assuming you are not talking about constant acceleration, which in itself iscontinuous. If you are talking about constant (meaning it's just a number, and not a function itself) acceleration, than just use the formula:v = i + at, wherev = velocity, i = initial velocity, a = acceleration, and t = timeOtherwise, you need to have some calculus knowledge. A velocity function is just the antiderivative (integral) of an acceleration function.Say, acceleration was given as:a = 2ttake the integral of thatv =∫ 2t dt = (2/2)t2+c =t2+cIn this case, the c is the initial velocity.Example:An object moves with an acceleration determined by a=t+3 (in m/s^2). Find the velocity of the object after 10 seconds have passed, given that the object has an initial velocity of 2 m/s.a = t + 3v =∫( t + 3) dt = (1/2)t2 + 3t + c, with c being initial velocityv(10 seconds) = (1/2)(10)2 + 3(10) + (2) = 82 m/s
Linear Velocity = Initial Velocity (m/s) + Acceleration (m/s2) * t 43.2 km/h
Using the acceleration formula, final acceleration is the final velocity minus the initial velocity over elapsed time. Final velocity you gave as 40m/s, and the initial velocity was zero (the apple was stationary on the tree), so the difference is 40 m/s. Divided by the time you gave, 4 s, this will be 10 m/sĀ²
It depends on what the initial velocity was. If it was 0, then: 11-0 = 2.2 m/s squared 5
