Answer:
20m/s²
Explanation:
force = mass*acceleration
acceleration = force ÷ mass
acceleration = 200N ÷ 10kg
acceleration = 20m/s²
Answer:
A. 20 N
Explanation:
Weight of the book = mass × acceleration due to gravity
= 2 × 10
= 20 N
Answer:

Explanation:
Given that,
Initial speed of a shuttlecock, u = 30 m/s
Final speed of the shuttlecock, v = 10 m/s
Time, t = 0.5 s
We need to find its average acceleration. The acceleration of an object is equal to the change in speed divided by time taken. It is given by :

So, the average acceleration of badminton shuttlecock is
.
I think it’s D I am sorry if I am wrong
Answer:
Unbalanced forces
Explanation:
Unbalanced forces acting on an object can change the object's speed, causing it to speed up or slow down.
