Explanation:
Whether you’re just getting started working out, or you’re looking to add strength training to your cardio routine, weight lifting for beginners can seem anything but simple. There’s a bunch of fitness equipment involved—how exactly do you use that big looped resistance band again?—the moves can be confusing, and you may worry that you might not have the strength to do them.
It’s true that weight lifting can appear intimidating—especially if you’re scrolling through social media and seeing people deadlifting double their bodyweight, pressing a loaded barbell over their head, or banging out Superman push-ups where they fly into the air. But it’s important to remember that those are just highlight reels of people who have been lifting for a very long time. When they first began, you can be pretty sure that they started small. Those explosive push-ups? It’s likely they started as a modified, knees-on-the-floor variation.
And strength training for beginners doesn’t have to start with the goal of getting you to that point, either. If you want to squat superheavy weight, beginning a strength training program can definitely help you get there. But it can also just help you get stronger in ways that will help you in everyday life, too, whether it’s carrying all the grocery bags into the house in one trip or squatting down to the floor to pick up your not-so-cuddly cat.

The combined mass of Danny+skateboard is 72.5 kg
Explanation:
We can solve the problem by using Newton's second law of motion:
where:
F is the net force applied on Danny and the skateboard
m is the mass of Danny+skateboard
a is the acceleration
Here we have the following data:
F = 29 N is the force applied
is the acceleration of Danny and the skateboard
Solving for m, we find their combined mass:
