Question

a car accelerates at 5.0 m/s² along a straight , horizontal road and reaches a velocity of 20 m/s in a ti.me of 4.0 s .
During this time its total displacement is 40 m
Which quantity is a scalar?
A a displacement of 40 m
B a time of 4.0 s
C a velocity of 20 m/s
D an acceleration of 5.0 m/s

Answer 1

Answer:

B a time of 4.0 s

Explanation:

scalar quantity is one which has value but no direction

Time has value but no direction

while velocity, acceleration and displacement have both value and direction
