3. What would be the mass of a truck if it is accelerating at a rate of 5 m/s and hits a parked car with a force of 14,000 N?
I

We are given both the Force applied by the truck and the acceleration of the  truck:

Force applied (F) = 14,000 N

Acceleration (a)=  5 m/s²

Solving for the mass of the truck:

From Newton's second law of motion,

F = ma    (where F is the force applied , m is the mass of the object and a is the acceleration of the object)

replacing the variables:

14000 = (m)* 5

m = 14000/5

m = 2800

Therefore, the mass of the truck is 2800 kg

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
