Over a time interval of 2.06 years, the velocity of a planet orbiting a distant star reverses direction, changing from +22.7 km/s to -22.1 km/s. Find (a) the total change in the planet's velocity (in m/s) and (b) its average acceleration (in m/s2) during this interval. Include the correct algebraic sign with your answers to convey the directions of the velocity and the acceleration. (a) Number Units (b) Number Units

A hockey goalie is standing on ice. Another player fires a puck (m = 0.170 kg) at the goalie with a velocity of +66.0 m/s. (a) If the goalie catches the puck with his glove in a time of 4.56×10−3 s, what is the magnitude of the average force exerted on the goalie by the puck? (b) Instead of catching the puck, the goalie slaps it with his stick and returns the puck straight back to the player with a velocity of -66.0 m/s. The puck and stick are in contact for a time of 4.56×10−3 s. Now, what is the magnitude of the average force exerted on the goalie by the puck? Verify that your answers to parts (a) and (b) are consistent with the conclusion of Conceptual Example 3. (a) Number Units (b) Number Units
