An 94.0 kg spacewalking astronaut pushes off a 655 kg satellite, exerting a 110 N force for the 0.470 s it takes him to straighten his arms.

4.A basket of food weighing 500 N is suspended at the end of a uniform rod 3.5 m long of mass 4.0 kg. A cable is connected to the center of the rod and has an angle 40 degrees with respect to the horizontal. A bear of mass 220 kg walks on the rod and tries to reach the food basket. a) Draw a free body diagram of the rod. b) If the maximum tension of the cable is 3800 N, where is the bear on the rod when the cable breaks? c) find the force that the wall on the rod right before the cable breaks. wall K 40⁰ Cable bear [/// & food basket

7. A box with cargo of known total mass m₁ can be moved up or down by a rope running around a pulley. The other end of the rope is attached to a block of mass m₂. The block of mass m₂ acts as a counterweight and that can slide on a ramp of known angle 0, as shown. The rope is massless, unstretchable, and slides without friction on the pulley. The pulley can be assumed to be massless and only changes the direction of the rope. m1 M2 Ө a. If the counterweight can slide without friction on the ramp, how does m₂ have to be chosen so that the cargo moves up or down with constant speed? b. If the coefficient of friction between the ramp and the counterweight is known to be µ, how does m₂ have to be chosen so that the cargo is lifted a height h from rest in a given time t₁? c. In the situation of (b), what is the tension in the rope?

A 686 N park ranger uses a basket and a rope-pulley system to transport an injured sea turtle up to a plateau, as shown in the figure. The sea turtle and basket together have a mass of 50.0 kg. The ranger holds firmly onto the rope and walks away from the cliff, speeding up at a steady rate of 0.300 m/2 2. He thereby causes the basket (and the turtle) to accelerate straight upwards at the same rate. Assume that the rope has negligible weight and that the pulley is ideal, having no friction in its bearing. Also assume that as the ranger trudges along, his feet do not slip on the ground. +x 26. The tension in the rope is equal to A. 490 N. B. 686 N. C. 475 N. D. 505 N. E. 196 N. 27. The frictional force which the ground exerts on the ranger's feet has a magnitude of C. 526 N. A. 490 N. B. 511 N. D. 196 N. E. 707 N.

If a man weighs 850N on the Earth, what would he weigh on Jupiter, where the free-fall acceleration is 25.9 m/s2? A 00-kg object undergoes an acceleration given by = (4.00 î + 9.00 ĵ) m/s2.  Find the resultant force and its magnitude acting on the object.

A 1am playing tug-o-war with my three nephews. The youngest in pulling with a force of 189 N. The middle child is pulling with a force of 334 N. The oldest is pulling with a force of 657 N. I am on a team with the youngest child. If I want to keep the four of us in equilibrium, how hard (in newtons) must I pull?

An 77.0 kg spacewalking astronaut pushes off a 650 kg satellite, exerting a 105 NN force for the 0.430 ss it takes him to straighten his arms. How far apart are the astronaut and the satellite 1.40 min after the push begins?

The distance between two telephone poles is 44.0 m. When a 1.00-kg bird lands on the telephone wire midway between the poles, the wire sags 0.180 m. Draw a free-body diagram of the bird. How much tension does the bird produce in the wire? Ignore the weight of the wire.

A mountain climber, in the process of crossing between two cliffs by the rope, pauses to rest. She weight 535 N. She is closer to the left cliff than to the right cliff. The left rope makes 600 and the right rope makes 800 with the vertical. Find the tensions in the rope to the left and to the right of the mountain climber.
