Both questions..# 10 an # 11 The coefficient of kinetic friction between a suitcase and the floor is 2.30, if the suitcase has a mass of 71.5 kg how far can it be pushed across the level floor A 0 35 kg pinecone falls 16 3 m to the ground, whore.t lands with a speed of 12 m/s. With what speed would the pinecone have landed If there had been no air resistance? Did air resistance do positive work, negative...
How much work is done on a 5 kg block if it is to be moved on a ramp 30° above the horizontal and height of 1 meter? What are the values of work done by each force?
a) how much work is done in raising a 50.0 kg crate a distance of 1.5 m above a storeroom floor? b) what is the change of potential energy as a result of this move? c) how much kinetic energy will the crate have as it falls and hits the floor? please show work
incase you can’t see the question, it says : How much work is done by the force if the object moves from x= 0.15m to x= 0.60m? (express your answer using two significant figures) Here we leam how to apply the force shown in the figure (Figure 1) moves an object nz0 to z 0.75 m. You may want to review ges 208-212) How much work is done by the force # the object moves from z-0.15 m to z...
1- How much work is done by the horizontal force Fp = 150N on the 18-kg block when the force pushes the block 5.0 m up along the 32° frictionless incline? (b) How much work is done by the gravitational force on the block during this displacement? (c) How much work is done by the normal force? (d) What is the speed of the block (assume that it is zero initially) after this displacement? [Hint: Work-energy involves net work done.]...
How much work is done when a 185 g tomato is lifted 10.6 m ? The tomato is dropped. What is the velocity, v, of the tomato when it hits the ground? Assume 90.9 % of the work done in Part A is transferred to kinetic energy, E, by the time the tomato hits the ground. Express your answer with the appropriate units.
