Answer:
0.119 s
Explanation:
Given that

Lets take final speed of the softball after covering 4.8 m = V
We know that

Also We know that

Putting the value of V ,U and a in the previous equation We get

Therefore slide time will be 0.119 s
In vacuum, going at 2.99×10^8 m/s.
Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
2 J / 4 C = 1/2 joule per coulomb.
That's 1/2 volt.
Answer:
Power, P = 162.53 Watts
Explanation:
Given that,
Mass, m = 200 g = 0.2 kg
Initial speed of the snake, u = 0
Final speed of the snake, v = 32 m/s
Time, t = 0.63 s
Power of an object is given by :




P = 162.53 Watts
So, the power of the rattlesnake is 162.53 Watts. Hence, this is the required solution.
