Find the velocity of a toy car that travels 8 meters in 19 seconds.
2. A car is driving at 21 m/s. The driver hits the gas and accelerates to 29 m/s in 2.6 seconds. What is the acceleration of the car?
3. A force of 87 N is applied to a box and causes it to accelerate at 4.3 m/s2. What is the mass of the box?
4. Find the weight in Newtons of a 55 kg object. (Remember the gravitational constant is 9.8 m/s2)
