Answer:
centripetal acceleration of the ball is 6.9 m/s/s
tangential speed of the ball is 2.2 m/s
Explanation:
As we know that ball complete 5 rotations in 10 seconds
so frequency of rotation of ball is given as

now we know that angular frequency is given as



Now centripetal acceleration is given as



now the velocity of the ball at this angular frequency is given as



Answer:
graph A
Explanation:
the slope of the distance-time graph is speed, speed is a scalar (with magnitudes but no direction)
but the slope for the velocity time graph is acceleration, acceleration is vector quantity ( has magnitude and direction)
Answer:
The speed of the cart and clay after the collision is 50 cm/s .
Explanation:
Given :
Mass of lump , m = 500 g = 0.5 kg .
Velocity of lump , v = 30 cm/s .
Mass of cart , M = 1 kg .
Velocity of cart , V = 60 cm/s .
We know by conservation of momentum :

Here ,
is the speed of the cart and clay after the collision .
Putting all value in above equation .
We get :

Hence , this is the required solution .
