7. How much force is needed to give a 10-kg mass an acceleration of 35 m/s?

Answer: 350 newton

Explanation:

Force needed = ?

mass = 10kg

Acceleration = 35m/s2 (The SI unit of acceleration is metre per second square)

Recall that Force is the product of mass of an object and the acceleration by which it moves.

Force = mass x acceleration

Force = 10kg x 35m/s2

Force = 350N

Thus, the force needed is 350 newton
