An object with a mass of 7kg gains the speed 26 meters per second after traveling the distance 2.8m. Calculate the resulting force that acts on it.

F = 845 [N]

Explanation:

To solve this problem we must use the following equation of kinematics.

where:

Vf = final velocity = 26 [m/s]

Vo = initial velocity = 0

a = acceleration [m/s²]

x = distance = 2.8[m]

Now we have to use Newton's second law which tells us that force is equal to the product of mass by acceleration.

ΣF = m*a

where:

F = force [N]

m = mass = 7 [kg]

a = acceleration = 120.71 [m/s²]

it becomes positively charged by charging it

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.
