Question1
A football player runs directly down the field for 26 m before turning to the right at an angle of 20 degrees from his new direction and running an added 12 m before being tackled.
What is magnitude of the runner's total displacement?
Answer in units of m.
Question2
A car of mass = 900 travelling at 40.0enters a banked turn covered with ice. The road is banked at an angle, and there is no friction between road and car's tires. Use = 9.80 throughout this problem. What is radius of the turn if = 20.0 (assuming the car continues in uniform circular motion around the turn)?
If 40 g of hot water at 80°C is poured into a cavity in a very large block of ice at 0°C, what will be the final temperature of the water in the cavity? Explain how much ice must melt in order to cool the hot water down to this temperature?
