Question

A soccer ball kicked with a force of 13.5 n accelerates at 6.5 m/s^2 to the right. what is the mass of the ball?

Answer 1

Answer:

2.08 kg

Explanation:

We can solve the problem by using Newton's second law:

$F=ma$

where

F is the net force acting on an object

m is the mass of the object

a is its acceleration

In this problem, the ball is kicked with a force of F=13.5 N, and its acceleration is a=6.5 m/s^2, therefore we can re-arrange the equation to find the mass of the ball, m:

$m=\frac{F}{a}=\frac{13.5 N}{6.5 m/s^2}=2.08 kg$

Answer 2

Answer: The mass of an ball is 2.08 kg.

Explanation:

Force is defined as the push or pull on an object with some mass that causes change in its velocity.

It is also defined as the mass multiplied by the acceleration of the object.

Mathematically,

$F=m\times a$

where,

F = force exerted on the ball = 13.5 N

m = mass of the ball = ?

a = acceleration of the ball = $6.5m/s^2$

Putting values in above equation, we get:

$13.5kg.m/s^2=m\times 6.5m/s^2\\\\m=\frac{13.5}{6.5}=2.08kg$

Hence, the mass of an object is 2.08 kg
