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

Based on the relationship between force, gravitational constant and mass:

Force is a pull or effect which tends to cause a change in the state or motion of an object.

1. Mass (m) = 32 kg

Acceleration (a) = 12 m/s² 

Force = 32 × 12

Force = 384 N

Mass (m) = 4 kg

Force (F) = 20 N

Acceleration (a) = Force/mass

Acceleration (a) = 20 ÷ 4

Acceleration (a) = 5 m/s²

The acceleration of the body of the object is found using the formula below:

where

u is the initial velocity

final velocity (v) = 30 m/s

time (t) = 3 seconds

mass (m) = 1500 kg

30 = 0 + 3a

30 = 3a

a = 30/3

a = 10 m/s²

Force = 1500 × 10

Force = 15000 N

The force of gravity that acting on the 20kg suitcase is the weight

Weight, W = mass × g

where g is the acceleration due to gravity

g = 9.8 m/s²

W = 20 × 9.8

Weight = 196 N

The moon gravitational constant is 1.6 m/s²

Force of gravity is given by W = m × g

Weight, W = 7 × 1.6

Weight, W = 11.2 N

The force of gravity is given by formula below:

The force of gravity = 100 N

The earth gravity constant = 9.8 m/s²

mass = 100 ÷ 9.8

Mass = 10.2 kg
