Phys 1L03 Tutorial session Set 5 Fifth series: Questions on Newton’s Laws For week of Feb 08, 2010 1. A girl pushed a 25 kg lawn mower as shown. If F= 30 N and θ = 37 o , a. What is the acceleration of the mower, and b. What is the normal force exerted on the mower by the lawn? Ignore friction. 2. In the ideal apparatus shown m 1 = 2.0 kg. What is m 2 if both masses are at rest? How about if both masses are moving at constant velocity? 3. A brick of mass 1.0 kg slides down an icy roof inclined at 30.0 o with respect to the horizontal. If the brick starts from rest, how fast is it moving when it reaches the edge of the roof 0.90 s later? Ignore friction. 4. Two blocks are connected by a cord that does not stretch. The cord passes over a frictionless pulley. If the masses are m 1 =26.0 kg and m 2 =42.0 kg, what are the accelerations of each block and the tension in the cord? 5. Consider the skier on a slope shown in figure. Her mass including equipment is 60.0 kg. a.
