Question

the relation between distance x and time t is x=2tsquare+2t. find velocity and acceleration

Answer 1

Hello

x = 2t^2 + 2t

Velocity = dx/dt  

=> dx/dt = 4t + 2

Velocity =  4t + 2

Acceleration = Dv/dt

=> 4 m/sec^2

:-)

Answer 2

x= 2 square + 2 t
by deviating x we will get velocity
v= DX/DT
2(2)t+ 2(1)
4t+2
again deviating x we will get acceleration
DV/dt
4 Meter / second square
