- A 2000-kg car traveling at 23 m/s takes 54 m to stop under full braking. The same car under similar similar road conditions, traveling at 35 m/s takes _________ m to stop under full braking.Question 26 Out of curiosity, a physics student checks the mass of their favorite chocolate bar, the Newton bar, and compares it to its biggest rival, the Hooke bar. The student notes that both bars should have the same mass since the values stamped on the wrappers by the manufacturers are the same, which are both 80.0 0.2 g. Using a digital scale in one of the physics labs, the student weighed 10 chocolate bars for each brand, and averaged the results for both and recorded the results in their notebook as: the Newton bar: (79.6 ± 0.2) g the Hooke bar: (79.7 ± 0.1) g Which of the following statements best describes the comparison between the two different chocolate bars masses, as well as the stamped value? O There is not enough information given to compare the two chocolate bars with each other, or the stamped value. There is not enough information given to compare the two chocolate bars with each other but they can be compared to the stamped value on the wrappers. ) The values for…A toddler pushes a play shopping cart around her room. Her mass is 14 kg, the cart is 5 kg and the items in the cart is 5kg. The toddler exerts a backward force on the floor of 60 N. Calculate the force the toddler exerts on the cart. All forces opposing the motion, such as the friction of the cart's wheels and air resistance, total 9 N.
