Ch 2.2 Help
I will fill in the blanks as answers get solved but seeing as this is old I doubt anybody needs them.
Question 1: (1 point)
An object moves for 8.435 s with an average acceleration of 4.384 m/s2. What is the change in velocity (see sheet 11)?
How to solve:
Question 2: (1 point)
An object moves with constant acceleration of 1.679 m/s2 for 4.318 s and reaches a final velocity of 50.19 m/s. What was its initial velocity (see sheet 13)?
How to solve:
Question 3: (1 point)
The position x of an object as a function of time is given as x = 6.098 + 4.082t + 15.45t2. All quantities are understood to be quoted in SI units. What is the initial velocity (see sheet 14 , 16)? Indicate with a negative (positive) sign whether the acceleration is constant (not constant) for the given expression.
How to solve:
Question 4: (1 point)
An object starting with 8.649 m/s is under a constant acceleration of 1.208 m/s2 over a distance of 6.846 m. What is the final velocity (see sheet 15 ,15' )?
