Answer:
153 N
Explanation:
The work done on the ball by the pitcher = Force * distance
The energy of the baseball is kinetic because it moves.
is the mass and is the velocity.
By the work-kinetic energic theorem,
Hence
Answer:
Evan drive at speed = 81.67 m/hr
Explanation:
Normal speed of Evan = 70 m/hr
Time taken by Evan to visit his grandmother = 35 min = hr
Distance covered by Evan = =
= miles
According to the problem, one day Evan was running 5 minutes late. So, the time Evan has to visit his grandmother is 30 mins.
To reach on time, Evan should be drive at the speed :
Speed =
=
= 81.67 m/hr
When a heavy football player and a light one run into each other, does the lighter player really exert as much force on the heavy player s the heavy player exerts on the light one. Yes. The interaction between the two players, the force each exerts on the other have equal strength.
Hope this helps you!!!
Please mark this as the brainliest one!!!
This isn’t anything related to physics dude
