Answer:
1700 W
Explanation:
Power = work / time
Power = force × distance / time
Power = force × velocity
P = (35 kg) (9.8 m/s²) (5 m/s)
P = 1700 W
5.2m/s
Explanation:
Given parameters:
Mass of baseball = 0.15kg
Momentum of baseball = 0.78kgm/s
Unknown:
Speed of baseball = ?
Solution:
The momentum of the baseball is a function of the product of the mass and velocity. It is a vector quantity:
Momentum = mass x velocity
Since the speed of the ball is unknown:
Velocity =
=
= 5.2m/s
The speed of the baseball before it lands is 5.2m/s

Answer:d
Explanation:
Given
First car is moving towards east with velocity 20 m/s
then it turns towards north then velocity is
suppose car takes t sec to change its path so average acceleration is given by
So average acceleration is towards North of west.
