A motorcycle with an initial velocity of 7.99x10^0 m/s accelerates for a total of 3.3x10^0 seconds at a rate of 1.51x10^0 m/s2. What is it's velocity, to two significant figures?
can anyone show the calculations for this

In 1998, NASA launched DS1 (Deep Space 1). This spacecraft successfully flew by the asteroid 1992 KD. The propulsion system worked by ejecting argon ions at high speed. The propulsion system could increase the velocity by 7.2284x10^0 m/s per day. What was the average acceleration in m/s2, expressed to 4 significant figures?
