Chapter 4, Problem 67P
A spider of mass ms drapes a silk thread of negligible mass over a stick with its far end a distance h off the ground, as shown in Fig. 4.26. A drop of dew lubricates the stick, making friction negligible. The spider waits on the ground until a fly of mass mf (mf > ms) lands on the other end of the silk and sticks to it. The spider immediately begins to climb her end of the silk, (a) With what acceleration must she climb to keep the fly from falling? If she climbs with acceleration as, at what height y will she encounter the fly?

- A bird is flying with a speed of 18.0(m)/(s ) over water when it accidentally drops a 2.00 Kg fish. If the altitude of the bird is 5.40 m and friction is ignored, what is the speed of the fish when it hits the water.arrow_forwardEmma and Katie are racing along in their new wagon. Upon reaching the bottom of the hill traveling at 13.2 m/s, Katie notices her teddy bear 12.0 m in front of them, panics and locks the brakes sending the wagon into a skid. If the wagon and its contents have a total mass of 1.50 x10^1 kg, and the coefficient of kinetic friction between the road and the rubber wagon tires is (0.75), by how much does the wagon miss the bear?arrow_forwardBank robbers have pushed a 1000 kg safe to a third-story floor-toceiling window. They plan to break the window and lower the safe 10.0 m to their truck. Not being too clever, they stack up 500 kg of furniture, tie a rope between the safe and the furniture, and place the rope over a pulley. Then they push the safe out of the window. The coefficient of kinetic friction between the furniture and the floor is 0.5. The rope would break if the force on it exceeds 5000 N. a) Does the rope break? b) What is the acceleration of the safe? c) What is the safe’s speed when it hits the truck?arrow_forward

The mattresses are compressed 2.00 m before she is brought to rest. Calculate the magnitude of the average force exerted by the mattresses on the stunt-woman.arrow_forwardWe are going to create a model for the forces acting when climbing with mass 'm' while falling on a rope. To simplify the problem, we will assume that there is no external or internal friction on the rope, and that there is no slack in the rope when the climber falls a height 'h/2' above the last belay, as shown in Figure. The rope has a length 'L' (in meters) when the fall occurs. All movement in the model is vertical (along the y-axis), and we will assume that the positive direction is downward. In part (a), the climber is in free fall until the rope starts to catch the fall. Set up the model for free fall and derive the expression for the velocity v0 that the climber has when the rope starts to slow down the fall. You can assume that the climber's speed is only a function of 'y' such that dy/dt = v(y)⟹ d²v/dt² = v * dv/dyarrow_forward

The lowest he can get his center of mass is 0.10 m above the ground, and the highest he can get it before he can no longer push against the ground is 0.40 m If the maximum force the dog can exert on the ground in pushing off is 2.1 times the gravitational force Earth exerts on him, how high can he jump?
