Jamal and Dayo are lifting a large chest, weighing 207 lb, by using the two rope handles attached to either side. As they lift and hold it up so that it is motionless, each handle makes a different angle with respect to the vertical side of the chest (Fig. P5.76). If the angle between Jamals handle and the vertical side is 25.0 and the angle between Dayos handle and the vertical side of the chest is 30.0, what are the tensions in each handle? FIGURE P5.76
A makeshift sign hangs by a wire that is extended over an ideal pulley and is wrapped around a large potted plant on the roof as shown in Figure P6.10. When first set up by the shopkeeper on a sunny and dry day, the sign and the pot are in equilibrium. Is it possible that the sign falls to the ground during a rainstorm while still remaining connected to the pot? What would have to be true for that to be possible? FIGURE P6.10 Problems 10 and 11.
The distance between two telephone poles is d = 54.0 m. When a 1.20 kg bird lands on the telephone wire midway between the poles, the wire sags h = 0.206 m. How much tension (in N) does the bird produce in the wire? Ignore the weight of the wire
Two forces, of magnitudes F1F1F_1 = 80.0 NN and F2F2F_2 = 50.0 NN , act in opposite directions on a block, which sits atop a frictionless surface, as shown in the figure. (Figure 1)Initially, the center of the block is at position xixix_i = -6.00 cmcm . At some later time, the block has moved to the right, and its center is at a new position, xfxfx_f = 5.00 cmcm .

There are two forces on the 1.19 kg box in the overhead view of the figure but only one is shown. For F1 = 15.7 N, a = 14.7 m/s2, and θ = 34.1°, find the second force (a) in unit-vector notation and as (b) a magnitude and (c) a direction. (State the direction as a negative angle measured from the +x direction.)
A parachutist (mass, m = 85 kg including parachute) has an initial velocity, v0 = 52.8 ms-1, immediately after the parachute opens. The drag force provided the parachute varies as a function of velocity, such that Fd = kv2 where k = 13.7 kg/m. Calculate the time it takes in seconds for the velocity to reach half the initial velocity. What is the maximum speed (terminal velocity) in km/h of the parachutist when the parachute is open?
the driver of a car on a horizontal road makesan emergency stop by applying the brakes so that all four wheelslock and skid along the road.The coefficient of kinetic friction betweentires and road is 0.40.The separation between the front andrear axles is L = 4.2 m, and the center of mass of the car is locatedat distance d =1.8 m behind the front axle and distance h = 0.75 mabove the road. The car weighs 11 kN. Find the magnitude of (a)the braking acceleration of the car, (b) the normal force on eachrear wheel, (c) the normal force on each front wheel, (d) the brakingforce on each rear wheel, and (e) the braking force on eachfront wheel. (Hint: Although the car is not in translational equilibrium,it is in rotational equilibrium.)
In the figure below, a runaway truck with failed brakes is moving downgrade at 36 m/s just before the driver steers the truck up a frictionless emergency escape ramp with an inclination of theta = 15°. The truck’s mass is 1.5 x 104 kg. (a) What minimum length L of the ramp must the ramp have if the truck is to stop at the top of the ramp at height h? (b) Does the minimum length L increase, decrease, or remain the same if the truck’s mass is decreased? Why? (c) If its speed is decreased? Why? Hint: Use Energy Principles.
In the very Dutch sport of Fierljeppen, athletes run up to a long pole and then use it to vault across a canal. At the very top of his arc, a 55 kg vaulter is moving at 2.5 m/s and is 5.1 m from the bottom end of the pole. What vertical force does the pole exert on the vaulter?
Two constant forces of magnitudes F1 and F2, act on a particle of mass 5.00 [kg] which is at rest at the origin. The force F1 points at 14.5° west of north, while the force F2, points at 58.3° west of south. Due to the two forces, the particle accelerates and is later located at 32.4 [m], 17.0° north of west with speed 12.2 [m/s]. What is F1?
Brian stands on one foot, and then lifts his heel off the floor by flexing his calf muscles. His Achilles' tendon connects the gastrocnemius and soleus (calf) muscles at a 75-degree angle to the calcaneus (heel), five cm from the axis, where his tibia (shin) joins with the callus (ankle). His metatarsals (toes) end fifteen em from this axis, with foot tilted 40-degrees from the ground. a.) Brian's mass m = 50kg is all held up by a normal force applied at his toes. How much torque does this force apply about the axis of his ankle? b.) What is the magnitude of the force Brians calf is exerting on his heel? Hint: Torques... about Ankle axis... c.) What are the magnitude and direction of the force that Brians tibia is applying to the ankle?
