What is the base unit to mass measurement

What is the final velocity of a 28 kg object that has an initial velocity of 5 m/s and has a force of 232 N exerted on in for 5.2 seconds? Do not leave a space between the units and the answer. No decimals-round to nearest whole number.

A car traveling 85 km/h slows down at a constant 0.53 m/s^2 just by "letting up on the gas." Calculate the distance it travels during the first second. Calculate the distance it travels during the fifth second.
