Question

An object with a mass of 17.5 kg accelerates 8.3 m/s2 when an unknown force is applied to it. What is the amount of the force?

Answer 1

GIVEN,

$\infty > \: \: mass \: of \: object = 17.5kg \\ \infty > \: acceleration = 8.3ms ^{ - 2}$

TO FIND,

$\infty > \: amount \: of \: force$

FORMULA USED,

$\infty > \: force \: = mass \: \times \: acceleration$

SOLUTION,

$\infty > \: force \: = \: mass \: \times \: acceleration \\ \\ \infty > \: force \: = 17.5 kg \: \times 8.3ms ^{ - 2} \\ \\ \infty > \: force \: = 145.25kg \: \times ms ^{ - 2} \\ \\ \infty > \: force \: = \: 145.25 \: newton$

Answer 2

Given,

• Mass = 17.5kg
• Acceleration = 8.3m/s^2

To Find:-

The amount of force

Formula used:-

F = ma (Newtons law)

F=Force

m=mass

a=acceleration

Calculations:-

F =ma

substitute the given values

F = 17.5×8.3

=145.25N

Hence,The force is 145.25N
