1. A 100 N box is supported in a motionless position
by two ropes that each makes 37° and
53° angles with the horizontal respectively. What is the magnitude of tension Ti and T2 in
the ropes? (Take: sin37° = cos53° =0.6, sin53° =COs37° =0.8) (2 points)

2. A block of mass 10 kg is placed on an inclined plane which makes an angle of 30° to the
horizontal. (2 points)
a) What is the acceleration of the block in sliding down the plane if friction is neglected?
b) In the presence of friction with HK = 0.5, what would be the acceleration of the block?
3. A car of mass 500kg travels at 20m/s. The car collides with a stationary truck of mass 1000kg. If
they stick together after collision, what is their common velocity? (1 points)
4. A constant force acts on a 600kg mass for 30sec. The velocity of the mass is 10m/s before the
mass is applied, and its final velocity is 20m/s. (2 points)
a) What impulse is produced?
b) What is the magnitude of the force?
5. A body at rest on a frictionless surface is struck by a second body. Is it possible that after
collision both bodies are at rest? Explain. ( 1 points)
