Question 1 of 11
The book has a mass of 2.5 kg.
What net force must act on the book to make it accelerate to the left at a rate
of 7.0 m/s2? (Hint: Use F = ma.)
O A. F = 17.5 N right
OB. F = 2.8 N right
O C. F = 2.8 N left
O D. F = 17.5 N left

Answer 1

Answer:

17.5 kg m/s

Explanation:

If F=ma

Then F = 2.5 X 7

Therefore F = 17.5 kg m/s is the net force needed to accelerate to the left.

Answer 2

Answer:

D. F= 17.5 N left
