. Your net force will be the crate's weight multiplied 2. and force in the x-direction will be 500N. You can then solve the equation for the friction force.
The farce the ball exert on the bat is reaction force. Reaction force always has the the exactly same magnitude as action force.
Answer: one of the things that determinates something is a planet and not a star is that planets are constanlty moving around the sun while stars are "still"
Explanation:
by the formula of spring force we know that
here we know that
now we will have
now by similar way if the stretch in spring is 0.25 m
force is given by
so it will require F = 250 N force
Explanation:
The distance between them is 200 km − 20 km = 180 km.
The relative velocity is 30 km/h − (-48 km/h) = 78 km/h.
The time it takes is 180 km / (78 km/h) = 2.31 hours, or 2 hrs 18 min.
Therefore, the trains meet at 9:30 AM.
