The acceleration of a particle is directly proportional to the square of the time t. When t =0, the particle is at x =24 m. Know

AlexFokin [52]

Answer:

x(t) = ⅟₁₀₈t⁴ + 10t + 24

v(t) = ⅟₂₇t³ + 10

Explanation:

a(t) = C₁t²

velocity is the integral of acceleration

v(t) = ⅓C₁t³ + C₂

position is the integral of velocity

x(t) = (⅟₁₂C₁)t⁴ + C₂t + C₃

x(0) = 24 = (⅟₁₂C₁)0⁴ + C₂0 + C₃

C₃ = 24

x(6) = 96 = (⅟₁₂C₁)6⁴ + C₂6 + 24

72 = 108C₁ + 6C₂

C₂ = 12 - 18C₁

v(6) = 18 = ⅓C₁6³ + C₂

18 = 72C₁ + C₂

18 = 72C₁ + (12 - 18C₁)

6 = 54C₁

C₁ = 1/9

C₂ = 12 - 18(1/9)

C₂ = 10

What is the value of the charge that experiences a force of 2.4 Ã— 10â€“3 n in an electric field of 6.8 Ã— 10â€“5 n/c?

tia_tia [17]

Answer:

The value of charge is 35.3 C

Explanation:

Given:

Force $F = 2.4 \times 10^{-3}$ N

Electric field $E = 6.8 \times 10^{-5} \frac{N}{C}$

According coulomb's law,

$F = qE$

Where $q =$ charge that experience a force,

For finding the value of charge,

$q = \frac{F}{E}$

$q = \frac{2.4 \times 10^{-3} }{6.8 \times 10^{-5} }$

$q = 35.3$ C

Therefore, the value of charge is 35.3 C
