A 180 cm long bar has a cross-sectional area of 1.8 × 10-4 m2. A force of 2.2 × 104 N applied to each end increases the length of the bar by 1.2 mm.  This is an example of what kind of strain?

A truck with a translational speed of 15.0 m/s rounds a curve with a radius of 6.50 m. Calculate the angular speed (units: radians per second).    NOTE: Watch correct use of rounding and significant figures Enter numerical answer in proper decimal format, not scientific notation Do not enter units with the answer  

A 1.25 × 103 g object is moving at 11.5 m/s. Calculate the momentum of the object (units: kg⋅m/s)?   NOTE: Watch correct use of rounding and significant figures Enter numerical answer in proper decimal format, not scientific notation Do not enter units with the answer  

Dave accelerates a box across a smooth friction-less horizontal surface over a distance of 15.0 m with a constant 25.0 N force angled at 38.0° above the horizontal. How much work (units: J) does Dave do on the box?

For each 25-point problem, provide 2 bulletpoints that explain your approach. For each 10-point problem, provide 1 bulletpoint that explains your approach.   Your explanations are also graded so these should not be 1-word bulletpoints.  They should demonstrate your understanding of the material.   Once you are done applying your derivative rules, you do not  have to simplify further.  This applies for all questions.
