Hayley is driving in her car going 24.0 m/s. A tree falls onto the road 112 meters ahead of her. Hayley doesn’t see it until 3.00 seconds later because she was texting and driving. When she finally does see it, she slams on the breaks decelerating at 7.48 m/s2. Determine if she will come to a complete stop before hitting the tree. Calculate how long does it take for the car to stop once she hits the brakes. How would I solve this?

An ice-making machine inside a refrigerator operates in a carnot cycle. it takes heat from liquid water at 0.0 degrees celsius and rejects heat to a room at a temperature of 19.2 degrees celsius. suppose that liquid water with a mass of 76.3kg at 0.0 degrees celsius is converted to ice at the same temperature. take the heat of fusion for water to be l_f = 3.34*10^5 j/kg.how much energy e must be supplied to the device? express your answer in joules.
