If given a distance of 83 meters, and an initial velocity of 2.2 m/s, how would you find the acceleration?

Question

Would you assume the final velocity to be zero?...and if anyone can help it will be greatly appreciated..for some reason these acceleration problems have been causing me problems..thanks

A hockey puck is sliding on a frozen lake and comes to rest after traveling 83 meters. If it's initial velocity is 2.2, what is the acceleration if it assumed to be constant?

What is the speed after traveling 26m?

Answer 1

Use the formula

2ax = Vf ² - Vi ²

where:
a = acceleration
x = displacement
Vf = final velocity
Vi = initial velocity

Solution:
2ax = Vf ² - Vi ²
2(a) (83m) = (0 m/s)² - ( 2.2m/s)²

166 a = 0 - 4.84

a = - 4.84/166

a = - 0.029 m/s²

a ≈ - 0.03 m/s²

Answer 2

You too can use one of the crucial following equations to remedy your challenge: v = u + at s = ut + (part)a(t^two) v^two = u^two + 2as u - preliminary velocity v - last speed a - acceleration s - displacement t - time The system on your venture is an application of the 3rd equation. Anticipate time, t=0 whilst x=6m. Then, v = 15 m/s u = 10 m/s s = 10-6 = 4m as a result, 225 = one hundred + two * four * a so ... A = (225-100)/eight = 100 twenty 5/eight = 15.625 m/s^two

Answer 3

you need final velocity, it will word it in the question (i.e...a body accelerated from.... to REST)
without final velocity, acceleration cannot be determined, unless other quantities are given, (say force, mass)

i would assume if you are given no information other than what you have, you should declare the answer unsolvable.
Unless you assume the question is asking the deceleration until friction slows it down entirely, but that would require the weight and all this other stuff.

Answer 4

Type in the exact problem so that we can read the information which is given. That way we can conclude if all the data was given or not.
