Question

a cricket ball of mass 160 grams traveling at 25m/s is intercepted by a player who fields it clearly in 0.2 seconds then the force exerted on his hands​

Answer 1

Answer:

mass=160gm

v=25m/s

t=0.2sec

u=0

therefore,

F=ma

hope it helps

Answer 2

Provided that:

• Mass of cricket ball = 160 g
• Initial velocity = 25 mps
• Final velocity = 0 mps
• Time = 0.2 seconds

To calculate:

• Force exerted

Solution:

• Force exerted = -20 N

Using concepts:

• Force formula.
• Formula to convert g-kg.

Knowledge required:

• SI unit of force = Newton.
• SI unit of time = seconds.
• SI unit of velocity = m/s
• SI unit of mass = kg.

Using formulas:

• Formula to convert grams into kilograms is mentioned below:

• 1 g = 1/1000 kg

• Formula to find force is mentioned below:

• F = m(v-u)/t

Where, F denotes force, m denotes mass, v denotes final velocity, u denotes initial velocity and t denotes time taken.

Required solution:

~ Firstly let us convert grams into kilograms by using suitable formula!

→ 1 g = 1/1000 kg

→ 160 g = 160/1000 kg

→ 160 g = 16/100 kg

→ 160 g = 0.16 kg

• Henceforth, converted!

~ Now let us find out the force by using suitable formula!

→ F = m(v-u)/t

→ F = 0.16(0-25)/0.2

→ F = 0.16(-25)/0.2

→ F = -4/0.2

→ F = -20 N

→ Force = -20 Newton

• Henceforth, solved!
