Cross country is a skiing muscular endurance because during the spring and the summertime start exercises of general muscular endurance (physical and gymnastic exercises) using a program of lower intensity without weights. Strength training is the kind of exercise that builds healthy muscle tissue. Strong muscles help you to move your body more efficiently, also become more coordinated and better able to perform technical movements.

Typical exercises could be: push-ups (1), bench dips (2), lunges (3), calf raise (4).

I hope i gave you a good understanding good luck!!

(2<br>Find the mass of an object if a force of 40N gives it acceleration of 2m^s

Rom4ik [11]

Answer:

m = 20 kg

Explanation:

Given that,

Force, F = 40 N

Acceleration of the object, a = 2 m/s²

We need to find the mass of the object. Let the mass be m.

We know that,

Net force, F = ma

So,

$m=\dfrac{F}{a}\\\\m=\dfrac{40}{2}\\\\m=20\ kg$

So, the mass of an object is equal to 20 kg.
