Question

A car moves in a straight line from rest at t=0 . Acceleration = 2 m/s^2. Time =?, Displacement =?, Velocity=10m/s.

Answer 1

Answer:

Explanation:

THE CAR STARTS FROM REST IMPLIES:

INITIAL VELOCITY ,U = 0 M/S

ACCELERATION, A= 2 M/S²

FINAL VELOCITY = 10 M/S

TIME , T=?

DISPLACEMENT , S=?

ACCORDING TO NEWTON' S LAWS OF MOTION:

V = U+AT

10 = 0+2*T

T = 5 SECONDS

DISPLACEMENT :

S = UT+1/2 AT²

S = 0*5+1/2*2*5*5

S = 0+25

S = 25 M

TIME TAKEN = 5 SECONDS .

DISPLACEMENT , S= 25 M.
