Two objects are connected by a string of negligible mass.(adsbygoogle = window.adsbygoogle || []).push({});

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!
