A 878-kg (1940 lb) dragster, starting from rest, attains a speed of 25.9 m/s (57.9 mph) in 0.62 s. (a) Find the average accelera

Answer:

41.8m/s^2

Explanation:

Since the dragster starts from rest, initial velocity (u) = 0m/s, final velocity (v) = 25.9m/s, time (t) = 0.62s

From the equations of motion, v = u + at

a = (v - u)/t = (25.9 - 0)/0.62 = 25.9/0.62 = 41.8m/s^2

Which change will always result in an increase in the gravitational force between two objects? increasing the masses of the obje
abruzzese [7]

By definition, we have that the gravitational force is given by:

F = \frac{G * m1 * m2}{r ^ 2}

Where,

G: gravitational constant

m1: mass of object number 1

m2: mass of object number 2

r: distance between both objects.

Therefore, for the gravitational force to increase, the following conditions must be met:

1) Increase the mass of the objects so that the numerator of the equation is greater.

2) Decrease the distance between the objects so that the denominator of the equation is smaller.

Answer:

A change that will always result in an increase in the gravitational force between two objects is:

increasing the masses of the objects and decreasing the distance between the objects
