Xander's friend Corey has a skateboard that he rides at Newton's Skate Park.

That's Corey doing a jump in the Figure below. The combined mass of Corey and

his skateboard is 60 kg. At the top of his jump, the net force acting on him is 30

Newtons. What is his acceleration at that moment?

0.5 m/s2

Explanation:

Step 1:

Data obtained from the question.

Total Mass = 60Kg

Net force = 30N

Acceleration = ?

Step 2

Determination of the acceleration.

Force = Mass x Acceleration.

With the above equation, we can easily obtain the acceleration as follow:

30 = 60 x Acceleration

Divide both side by 60

Acceleration = 30/60

Acceleration = 0.5 m/s2

Now, we can thus say that the acceleration at that moment is 0.5 m/s2
