A spring scale shows a net force of 0.8 N acting on a 1.5-kg mass. What happens to the acceleration of the object if the net force is decreased to 0.2 N? The acceleration decreases to a quarter of its original value, or about 2 13 m/s2

The acceleration decreases to a quarter of its original value, or about 0.13 m/s2

The acceleration increases to four times its orginal value, or about 0.13 m/s2

The acceleration increases to four times its original value, or about 2.13 m/s2

c.the charges if the proton and electron and gravity

truck y has a greater velocity than truck x.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
