Question

Calculate the force needed to speed up a car with a rate of 5ms–2, if the mass of the car is 1000 kg. Solution: According to question: Acceleration (a) =5m/s2 = 5 m / s 2 and Mass (m) = 1000 kg, therefore, Force (F) =?

Answer 1

Answer:

Force = mass × acceleration

given , acceleration, a = 5m/s²

mass, m = 1000kg

Force = 1000×5

= 5000 N

Answer 2

Explanation:

m = 1000kg

a=5m/s-2

f=1000kg

answer : F=M.A

F=1000kg x5m/s-2

F=5000N
