Question

part 1 of 2 Consider the acceleration of a particle along a straight line with an initial position of 8m and an initial velocity of 3 m/s. acceleration (m/s²) what is the velocity at 1 s​

Answer 1

Using, s=ut+

2

1

at

s

1

=u+

1

a

or, 3=u+

2

a

∴a=6−2u

s

2

=2u+

1

a×4

8=2u+2a

Solving the equations

8=2u+2(6−2u)

8=2u+12−4u

2u=4

u=2m/s

∴a=6−2u=6−4=2m/s
