2 kg toy car moves at a speed of 5 m/s. B. If a child applies a 3 N force for 2 m in the same direction the car is already moving, how much work is done on the car?

c. What is the change in the car’s kinetic energy from the applied force?

d. What is the final kinetic energy of the car?

e. What is the velocity of the car after the child applies the 3 N force?

If gases like carbon dioxide and methane make up less than 1% of the total atmosphere, why is it important for scientists to monitor changes in percentages of these gases?

Asystematic approach to problem solving is called a (an)

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.
