Question

The formula v= u+ atdescribes connections between u: starting velocity a: acceleration t: time v: final velocity a)In a particular situation, u= 0, v= 49 and a= 9.8. Substitute these numbers into the formula to create an equation. b)Solve the equation to find the value of t

Answer 1

• 49 = 0 +9.8t
• t = 5

Explanation:

It usually works to follow directions.

a) Substitute the numbers into the formula:

v = u + at

49 = 0 +9.8t

b) Solve the equation:

49/9.8 = t = 5 . . . . . divide by the coefficient of t
