Ans: Thus, the kinetic energy change = 4.5 J
The mass of puppy = 3kg
Kinetic energy initial =
=
Kinetic energy final =
Thus, the kinetic energy change = 4.5 J
The mass of puppy = 3kg
Kinetic energy initial =
=
Kinetic energy final =
Thus, the kinetic energy change = 4.5 J
Answer:
(I). The sum of the vectors is (7i-5j).
(II). The sum of the vectors is (8i+7j).
Explanation:
Given that,
(I). Vector A
Vector B
Suppose, (II). Vector A
Vector B
(I). We need to calculate the sum of the vectors
Using formula of sum
Where,
(II). We need to calculate the sum of the vectors
Using formula of sum
Put the value into the formula
Hence, The sum of the vectors is (7i-5j).
The sum of the vectors is (8i+7j).
