Answer:

**Answer:**

False

whenever the string breaks, the ball will follow the straight line tangential path

**Explanation:**

No, the ball will not follow a curved path after the string breaks. Since, the the direction of velocity is tangential to each point of the circular motion. Therefore, it changes at every point. This produces an acceleration in the circle called centripetal acceleration. There is also a tangential component of acceleration acting on the ball during this motion.

**So, whenever the string breaks, the ball will follow the straight line tangential path. Hence, the given statement is false.**

**Answer:**

The mass of the object is approximately 70.79 kilograms

**Explanation:**

We use Newton's second law to solve this problem. This law states that the net force on an object equals the product of its mass times the acceleration:

Therefore, for this case, since the net force on the object and its acceleration are given, we can use the equation above to solve for the unknown mass:

**Answer:**

ball clears the net

**Explanation:**

= initial speed of launch of the ball = 20 ms^{-1}

= angle of launch = 5 deg

Consider the motion of the ball along the horizontal direction

= initial velocity =

= time of travel

= horizontal displacement of the ball to reach the net = 7 m

Since there is no acceleration along the horizontal direction, we have

Eq-1

Consider the motion of the ball along the vertical direction

= initial velocity =

= time of travel

= Initial position of the ball at the time of launch = 2 m

= Final position of the ball at time "t"

= acceleration in down direction = - 9.8 ms⁻²

Along the vertical direction , position at any time is given as

Since Y > 1 m

hence the ball clears the net

**Answer:**

a) Revolutions per minute = 2.33

b) Centripetal acceleration = 11649.44 m/s²

**Explanation:**

a) Angular velocity is the ratio of linear velocity and radius.

Here linear velocity = 72 m/s

Radius, r = 0.89 x 0. 5 = 0.445 m

Angular velocity

Frequency

Revolutions per minute = 2.33

b) Centripetal acceleration

Here linear velocity = 72 m/s

Radius, r = 0.445 m

Substituting

Centripetal acceleration = 11649.44m/s²

**Answer:**

The work done in stretching the spring is 0.875 J.

**Explanation:**

**Given that,**

Force = 140 N

Natural length = 60-40 = 20 cm

Stretch length of the spring = 65-60 = 5 cm

**We need to calculate the spring constant**

**Using formula of Hooke's law**

**We need to calculate the work done**

On integration

**Hence, The work done in stretching the spring is 0.875 J.**
