Part A What is the acceleration of the bowling ball, in magnitude and direction, at this instant? / ms 2 Part B What is the tension in the rope at this instant? N Problem 5.72 Block A in the figure ( Figure 1 ) weighs 68.2 N . The coefficient of static friction between the block and the surface on which it rests is 0.29. The weight w is 10.1 N and the system is in equilibrium. Exercise 6.5 A 75.0- kg painter climbs a ladder that is 2.71 m long 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 Submit My Answers Give 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 ⃗ =( 29 N ) i ^−( 35 N ) j ^ to the cart as it undergoes a displacement s ⃗ =(− 8.8 m ) i ^−( 3.7 m ) j ^ . Part A How much work does the force you apply do on the grocery cart?
