Question

CLASS WORK. A truck starts from rest and moves with a constant acceleration of 5ms^-2 for 20 seconds. Calculate; a. Final velocity of the truck; b. The distance it travels after 20 seconds. TIME: 10 MINUTES. you can start.

Answer 1

Answer:

Explanation:

STARTING FROM REST

INITIAL VELOCITY , U = 0 M/S

ACCELERATION, A= 5 M/S²

TIME TAKEN , T = 20 SEC

[A] FINAL VELOCITY, V= ?

ACCORDING TO NEWTON'S LAW :

V = U+AT

V = 0+5*20

V = 100 M/S

[B] DISTANCE TRAVELLED,S =?

S = U T +0.5 AT²

S = 0*20 + 0.5*5*20*20

S = 0.5*100*20

S = 1000 M.
