Answer:

≈ 20.35 N [newton's of tension]

Explanation:

( (2.9 × 9.8) ÷ cos(35.6°) ) × sin (35.6°) =

( (28.42) ÷ (≈0.813) ) × (≈0.582) =

(≈34.96) × (≈0.582) = 20.3449446.... ≈ 20.35

A man pushes a 10kg box with a constant acceleration of 5m/s2. What force is applied to the box?

drek231 [11]

FORMULA

$\boxed {F = m \times a}$

F = force
m = mass
a = acceleration

Using the formula

$F = 10 \times 5$

Multiply

$\boxed {\textsf {F = 10 N}}$

Answer:

The answer to your question is Equation vf = gt; vf = 29.6 m/s

Explanation:

Data

gravity = 3.7 m/s²

vf = ?

time = t = 8 s

Formula

vf = vo + gt

Initial speed = 0 m/s

To solve this problem we can use the equations of free fall and just substitute the data.

- Substitution

vf = 0 + (3.7)(8)

- Simplification

vf = 29.6 m/s
