Problem 4: A particle moves along the path s at a constant speed, as shown in Figure 4 below. The mass of the particle is 1 kg. Based on this information, answer the following questions. 1. What is the magnitude of the acceleration at the instant shown? 2. The speed is constant, but the acceleration you found should be non-zero. Explain why this is. What is the net force acting on the particle in the tangential direction? What is the net force acting in the normal direction? v = 10 m/sec p = 15 m S Figure 4: Particle traveling along paths.
