What is the tension in the rope at this instant? N Problem 5.72 Block A in the figure (Figure 1) weighs 68.2N . The coefficient of static friction between the block and the surface on which it rests is 0.29. The weight w is 10.1N and the system is in equilibrium. Exercise 6.5
A 75.0-kg painter climbs a ladder that is 2.71mlong leaning against a vertical wall. The ladder makes an 26.0 ∘ angle with the wall. Part A How much work does gravity do on the painter? W = J SubmitMy AnswersGive Up Part B Does the answer to part A depend on whether the painter climbs at constant speed or accelerates up the ladder?
Does the answer to part A depend on whether the painter climbs at constant speed or accelerates up the ladder? Yes No Exercise 6.8 A loaded grocery cart is rolling across a parking lot in a strong wind. You apply a constant force F ⃗ =( 29N ) i ^−( 35N )
j ^ to the cart as it undergoes a displacement s ⃗ =(− 8.8m ) i ^−(3.7m ) j ^. Part A How much work does the force you apply do on the grocery cart?
