Ch 2.3 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, initially at rest, falls under the influence of gravity (neglect air resistance) and reaches a speed of 8.34 m/s. For how many seconds did it fall (see sheet 19)? Indicate with a positive (negative) sign whether with air resistance the fall time is smaller (larger) than without air resistance.
How to solve:
Question 2: (1 point)
An object, initially at rest falls under the influence of gravity (neglect air resistance) a distance of 3.883 m. How many seconds does it fall (see sheet 19)?
How to solve:
Question 3: (1 point)
An object is tossed vertically downward from an 70.42 m height and reaches the ground after 2.715 seconds. What was the magnitude of its initial velocity from the toss (neglect air resistance, see sheet 14)?
How to solve:
Question 4: (1 point)
An object is launched vertically upward with 6.871 m/s. How high does it rise (neglect air resistance , see sheet 23' )?
