The equation is:
The impulse done by the engine is given by the following integral:
Answer:
t = 1min
Explanation:
count how many footballs there are
Answer:
Explanation:
Given that
F(x) = (2.00 N/m) x +(1.00 N/m3) x3.
Which can be written as
F(x) = 2x +x³ N/m
Potential energy from x=1 to x=2
P.E is given as
P.E=∫F(x)dx
P.E=∫2x+x³ dx. From x=1 to x=2
P.E= 2x²/2 + x⁴/4 from x=1 to x=2
P.E= x² + x⁴/4 from x=1 to x=2
P.E=(2²+2⁴/4)-(1² +1⁴/4)
P.E=(4+4)-(1+1/4)
P.E, =8-5/4
P.E=27/4
P.E=6.75J
Since it is moving from lower position to upper position, then P.E should be negative
P.E = - 6.75J
