Question

Displacement s is related with time t by the equation s = 5t2 + 4t + 3. The acceleration of the particle is

Answer 1

Explanation:

$s = 5 {t}^{2} + 4t + 3$

V=ds/dt

$= d(5 {t}^{2} + 4t + 3) \div dt$

v = 10t+4

now, A= dv/dt

=d(10t+4)/dt

= 10

hence acceleration = 10 m/s^2

Answer 2

acceleration = 10 m/s^2
