Background story: Karla, Matthew, Daneisha, Vince and Sergio all have carts of different masses. In their lab, they each apply a different amount of force to their carts, resulting in different accelerations. Yikes! They did not label their data table and are now trying to backtrack and identify all of their data. Your task: using the clues below and your understanding of Newton’s 2nd Law of Motion (F=ma), help each student determine the mass of their cart, the acceleration of their cart, and the force they each gave their cart. What the students know: • the carts had masses of 6 kg, 4.5 kg, 9 kg, 10 kg and 12 kg • the carts had
accelerations of 5 m/s2 , 3 m/s2 , 2 m/s2 , 4 m/s2 , and 2.5 m/s2.
Clues: 1) Karla’s cart is half the mass of Daneisha’s cart.
2) The mass of Vince’s cart is neither the smallest nor the largest.
3) The mass of Sergio’s cart is greater than the mass of Vince’s cart.
4) The acceleration of Daneisha’s cart was half the acceleration of Sergio’s cart.
5) The force Vince applied to his cart was larger than the force that Matthew applied to his cart.
6) The acceleration of Matthew’s cart was greater the acceleration of Vince’s cart.
7) Karla applied less than 18 N of force to her cart.

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
