A charge of -3.50 nC is placed at the origin of an xy-coordinate system, and a charge of 1.95 nC is placed on the y axis at y = 3.55 cm. Part A
If a third charge, of 5.00 nC, is now placed at the point x = 2.85 cm , y = 3.55 cm find the x and y
components of the total force exerted on this charge by the other two charges.
Part B
Find the magnitude of this force.
Part C
Find the direction of this force.

Asap i'm in class rn a 1,000-kg car is traveling 20 m/s on a flat stretch of road. it gets to a hill and coasts uphill until it stops. how high up the hill does the car travel? givens: equation: 1/2mv2initial=mghfinal solve for h. plug & chug, label.

If a hiker that weighs 600 newtons climbs a 50 meter hill, how much gravitational potential energy has the hiker gained?

You have been hired to design a spring-launched roller coaster thatwill carry two passengers per car. the car goes up a 10-m highhill, then descends 15m to the track's lowest point. you'vedetermined that the spring can be compressed a maximum o 2.0m andthat a loaded car will have a maximum mass of 400kg. for safetyreasons, the spring constant should be 10% larger than the minimumneeded for the car to just make it over the top. a) what spring constant (k) should you specify ? b) what is the maximum speed of a 350 kg car if the spring iscompressed the full amount.
