. Imagine a demo car of total mass 51.0 kg includes nitro boost fuel of 1.0 kg. The car is initially accelerating at the rate of 2.0 m/s2. When the nitro boost is powered on, the new
acceleration is 4.0 m/sFind out the change in force just prior to firing the nitro and just after
the fuel is exhausted.

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.
