The momentum of an object is the product between the mass m of the object and its velocity:
The truck in our problem has momentum equal to
and a mass of
so, if we re-arrange the previous formula, we can use these data to find the velocity of the truck:
Answer:
N
Explanation:
We are given that
Mass of baseball=m=0.145 kg
Initial velocity of ball=u=43 m/s
Speed, v=
Time, t=1.71 ms=
Horizontal component of the average force on the ball=
Horizontal component of the average force on the ball
Horizontal component of the average force on the ball=N
Answer:
Nothing is more important to us on Earth than the Sun. Without the Sun's heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.
