While a roofer is working on a roof that slants at 38.0 ∘∘ above the horizontal, he accidentally nudges his 87.0 NN toolbox, causing it to start sliding downward, starting from rest. If it starts 4.65 mm from the lower edge of the roof, how fast will the toolbox be moving just as it reaches the edge of the roof if the kinetic friction force on it is 18.0 NN?

While a roofer is working on a roof that slants at 42.0 ∘∘ above the horizontal, he accidentally nudges his 89.0 NN toolbox, causing it to start sliding downward, starting from rest. If it starts 4.90 m from the lower edge of the roof, how fast will the toolbox be moving just as it reaches the edge of the roof if the kinetic friction force on it is 19.0 N?
Keep the track tilted at 13∘∘ with the horizontal. Put the friction block on the track surface at the top of the track. Let the friction block slide downwards. The length of the track is 74 cm. Starting from zero speed at the top of the track, what will be the speed of the friction block as it reaches the bottom? Write your answer in m/s. Use μμk = 0.13 and mass of the friction block = 400 grams.
While a roofer is working on a roof that slants at 32° above the horizontal, he accidentally nudges his 73N toolbox, causing it to start sliding downward, starting from rest. If it starts 5m from the lower edge of the roof, how fast will the toolbox be moving just as it reaches the edge of the roof if the kinetic friction force on it is 18N? Answer: 5.27m/s
A 60.0 kg skier with an initial speed of 15 m/s coasts up a 2.50 m high rise as shown in the figure. a. Find her final speed right at the top, in meters per second, given that the coefficient of friction between her skis and the snow is 0.36.
Gayle runs at a speed of 3.20 m/s and dives on a sled, initially at rest on the top of a frictionless snow-covered hill. After she has descended a vertical distance of 5.00 m, her brother, who is initially at rest, hops on her back and together they continue down the hill. What is their speed at the bottom of the hill if the total vertical drop is med ocum 15.0 m? Gayle's mass is 49.5 kg, the sled has a mass of 5.45 kg and her brother has a mass of 30.0 kg. m/s Need Help? Read It gy
