Aforce of 45 n isvexerted on an object, resulting in an acceleration of 5 m/s^2 for the object what will the objects acceleration be if the force doubles

the acceleration will be 10 m/s^2

Explanation:

the force applied to an object and the acceleration of the object are directly proportional, as Newton's second law states:

where

F is the net force applied to the object

m is the object's mass

a is the object's acceleration

in the first example, a force F=45 N is applied to the object, giving it an acceleration of a=5 m/s^2. Therefore, the mass of the object is

In the second example, the force is doubled, so it will be F=90 N. The mass is still m=9 kg, so the acceleration will be

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h
