Question

Q4 a body starting from rest attains a velocity of 20m/s in 10 seconds. Find its acceleration and the distance
moved by it in this time
Q5. A body comes to rest after moving a distance of 4m with an acceleration of 2m/s Find its initial velocity
Q6. State Newton's first law of motion with one example,
07. A car moves on a straight track with uniform motion. It has a velocity of 18m/s. What is its velocity after
15 seconds?
Q8. Derive second and third equation of motion graphically,
09. Explain Newton's third law of motion.​

Answer 1

Answer:

Q4:

Explanation:

acceleration = velocity / time

= 20/10

= 2 meret per second square

Distance = velocity * time

= 20*10

= 200 meter

Answer 2

Answer:

(4) a=2,s=100m

(5) u=4

(7) 18

Explanation:

by using newtons 1,2,3 laws motion

let..

u=initial velocity

v=final velocity

a=acceleration

s=distance
