Problem 1
A train covers 60 miles between 2 p.m. and 4 p.m. How fast was it
going at 3 p.m.?
Solution:
The speed is traveled distance (60 miles) divided by traveled time
(4pm 2pm = 2hours):
Problem 2
Is it possible that the car could have accelerated to 5
Problem 6
A 8 kg block is at rest on a horizontal floor. If you push horizontally
on the 8 kg block with a force of 20 N, it just starts to move.
(a) What is the coefficient of static friction?
(b) A 10.0 kg block is stacked on top of the 8 kg block. What
