A student ate a Thanksgiving dinner that totaled 3000Cal . He wants to use up all that energy by lifting a 30-kg mass a distance of 1.0 m. Assume that he lifts the mass with constant velocity and no work is required in lowering the mass.
A- How many times must he lift the mass?
B- If he can lift and lower the mass once every 4.8s , how long does this exercise take?
A toy cork gun contains a spring whose spring constant is 10.02 N/m. The spring is compressed 5.0 cm and then used to propel a 6.00 g cork. The cork, however, sticks to the spring for 1 cm beyond its unstretched length before separation occurs. The m..
