Two objects are connected by a string of negligible mass.
The 10 kg block is placed on a
smooth table top 2.2 m above the floor, and
the 8 kg block hangs over the edge of the ta-
ble. The 8 kg block is then released from rest
at a distance of 1.1 m above the floor at time
t = 0.
A. Determine the acceleration of the 8 kg block
as it descends. The acceleration of gravity is
9.8 m/s2 .
Answer in units of m/s2.
B. How long dies it take the 8 kg block to strike
the floor?
Answer in units of s.
C. Describe the motion of the 10 kg block from
the time t = 0 to the time when the 8 kg block
strikes the floor.
1. Itmoves with an increasing acceleration.
2. It moves with a constant speed.
3. It moves with a decreasing acceleration.
4. It moves with a constant acceleration.
5. It stays still.
D. Describe the motion of the 10 kg block from
the time the 8 kg block strikes the floor to the
time the 10 kg block leaves the table.
1. Itmoves with an increasing acceleration.
2. It stays still.
3. It moves with a constant speed.
4. It moves with a decreasing acceleration.
5. It moves with a constant acceleration.
E. Determine the distance between the landing
points of the two blocks.
Answer in units of m.
I've tried this question multiple times and got it wrong... :( I need help!
