A 75 kg person in a frictionless environment throws a 5 kg ball with a force of 15 N

What is the acceleration of the ball & the person?

Two students tug - o -war. One pulls with a force of 5 Newtons to the right, one pulls with a force of 7 Newtons to the left. Which way does the rope move?

Two students push a car out of the mud. One pushes with 10 Newtons, the other with 7 Newtons. Will they overcome the friction force of 15 Newtons?

In Figure 4.7, the net external force on the 24-kg mower is stated to be 51 N. If the force of friction opposing the motion is 24 N, what force (in newtons) is the person exerting on the mower? Suppose the mower is moving at 1.5 m/s when the force is removed. How far will the mower go before stopping?

In the figure, the net external force on the 24 kg mower is known to be 51 N. If the force of friction opposing the motion is 24 N, what force F (in newtons) is the person exerting on the mower? Suppose the mower is moving at 1.5 m/s when the force F is removed, how far will the mower go before stopping?

The helicopter view in Fig. P3.15 shows two people pulling on a -I. stubborn mule. The person on the right pulls with a force F i of magnitude 120 X and direction of B1= 60.0°. The person on the left pulls with a force it2 of magnitude 80.0 N and direction of 02 = 75.0°. Find (a) the single force that is equivalent to the two forces shown and (b) the force that a third person would have to exert on the mule to make the resultant force equal to zero. The forces are measured in units of newtons (symbolized N).
