1) A 170g wood block is firmly attached to a very light horizontal spring, as shown in the figure. The block can slide along a table where the coefficient of friction is 0.23. A force of 29N compresses the spring 12cm.
- If the spring is released from this position, how far beyond its equilibrium position will it stretch on its first cycle?
2) Determine the escape velocity from the Sun for an object at the Sun's surface (r=7.0×105km, M=2.0×1030kg).
Determine the escape velocity from the Sun for an object at the average distance of the Earth (1.50×108km).
