Step-by-step explanation:
Answer:
1.) 15.24 J
2.) 7.62 W
Step-by-step explanation:
Given that You do a pull-up, lifting yourself by 0.5 in 2 seconds. If your weight is 600 N,
Convert inches into metres
1 inches = 0.0254 metres
Work done = Force × distance
Work done = 600 × 0.0254
Work done = 15.24 J
Power is the rate at which work is done.
That is,
P = WD / time
Power = 15.24 / 2
Power = 7.62 W
Therefore, 15.24 Joule of work done must be done and 7.62 watt of power output must be required to lift the yourself.
Factor by grouping. Group up the terms into pairs, factor each pair, then factor out the overall GCF.
x^3 + 2x^2 - 16x - 32
(x^3 + 2x^2) + (-16x-32) ... pair up terms
x^2(x + 2) + (-16x - 32) ... factor x^2 from the first group
x^2(x + 2) - 16(x + 2) ... factor -16 from the second group
(x^2 - 16)(x + 2) .... factor out (x+2)
(x - 4)(x + 4)(x + 2) .... Use the difference of squares to factor x^2-16
---------------------------
The original expression completely factors to (x - 4)(x + 4)(x + 2)
The three factors are x - 4 and x + 4 and x + 2
