Question

1.The essential part of the Hot Wheels speed booster is made of two fast spinning, rubberized disks of radius r=0.046 m each. The toy car entering the booster is in direct contact with both wheels, which send it away after brief encounter with it. When the speed booster is set up horizontally at the edge of a table (h=0.99 m) it sends the car in the projectile motion so that it lands at horizontal distance of x=1.66 m away from the edge of the table. Use this information to find the angular velocity of the spinning disks in the booster. Give your answer in rpm -- revolutions per minute. Round your answer to 0 decimal Answer Save Answer 2. Q2a: Lets play with Hot Wheels again (Points: 5) When the speed booster is set up horizontally at the edge of a table (h=1.15 m) it sends a toy car of mass m=0.07kg in the projectile motion, so that it lands at horizontal distance of x1=1.33 m away from the edge of the table. When the sam car with the same speed booster are used but the car is made to go through the loop-the-loop track before it is send away from the edge of the table, it lands at distance x2=1.01. Use this information to find the energy lost by the car while making the vertical loop. Calculate your answer to 3 decimal places Answer Save Answer

Explanation / Answer

The essential part of the Hot Wheels speed booster is made of two fast spinning, rubberized disks of radius r=0.032 m each. The toy car entering the booster is in direct contact with both wheels, which send it away after brief encounter with it. When the speed booster is set up horizontally at the edge of a table (h=1.02 m) it sends the car in the projectile motion so that it lands at horizontal distance of x=1.60 m away from the edge of the table. Use this information to find the angular velocity of the spinning disks in the booster. Give your answer in rpm — revolutions per minute.
