What force (in newtons) is required to accelerate a body with a mass of 32 kilograms at a rate of 12 m/s2? if a body with a mass of 4 kg is moved by a force of 20 n, what is the rate of its acceleration? a car with a mass of 1,500 kg is traveling at a speed of 30 m/s. what force must be applied to stop the car in 3 seconds? if a suitcase has a mass of 20 kg, what is the force of gravity acting on it? on the moon, what would be the force of gravity acting on an object that has a mass of 7 kg? on earth, what is a child’s mass if the force of gravity on the child’s body is 100 n? plse me asap. i will mark you brainliest for correct answers

An alpha particle with kinetic energy 12.5 mev makes a collision with lead nucleus, but it is not "aimed" at the center of the lead nucleus, and has an initial nonzero angular momentum (with respect to the stationary lead nucleus) of magnitude l = p0 b, where p0 is the magnitude of the initial momentum of the alpha particle and b=1.40×10−12 m. (assume that the lead nucleus remains stationary and that it may be treated as a point charge. the atomic number of lead is 82. the alpha particle is a helium nucleus, with atomic number 2.) what is the distance of closest approach?
