Answer:
D) 24m, 300o
Explanation:
The vector A has magnitude of 12 m and it makes 120 degree with + ve x axis
So it can be represented by the vector as follows
A = 12 Cos 120 i + 12 sin 120 j
vector 2A = 24 Cos 120 i + 24 sin 120 j
- 2A = - 24 Cos 120 i - 24 sin 120 j
= 24 Cos ( 180 -120 ) - 24 sin ( 180 -120)
= 24 Cos 60 - 24 sin 60
= 24 Cos ( 360 - 60 ) + 24 sin ( 360 -60 )
= 24 Cos 300 + 24 sin 300
It represents a vector having magnitude of 24 and making 300 degree with + ve x- axes in anticlockwise direction.
The amount of work will decrease as the force decreases because work is equal to force multiplied by displacement.
Answer:
The ball exerts a force of 400 N on the bat.
Explanation:
Given that,
A baseball player hits a ball with 400 N of force.
We need to find the force the ball exert on the bat.
We know that,
According to Newton's third law, when object 1 exerts a force on an object 2, then object 2 will exert a force on object 1 but in opposite direction.
So, the ball exerts a force of 400 N on the bat.
