Question

a car acquires a velocity of 72 km/he in 10 sec starting form rest.(1) find its acceleration. (2)average velocity. (3)distance travelled by the body. ​

Answer 1

ANSWER :

u = 0 m/'s

v = 72 km/hr = 20 m/'s

t = 10 's

a = 20 - 0/10

= 20/10

= 2 m/s^2

s = 1/2 at^2

.

= 1/2 × 2 × 10

= 10 m

Average velocity = displacement /time

= 10/10

= 1 m/s
