A 850 kg car is traveling at a constant speed of 14 m/s around a bend with a radius of 180 m. Calculate: a) the centripetal acceleration of the car.
b) the centripetal force acting on the car.
c) What actual force provides the centripetal force for the car to round the bend?

It is really hard for me right know

How many neutrons does element x if it’s atomic number is 28 and its mass number is 87

1which body contains the majority of the mass in the solar system earth jupiter the moon the sun 2 what keeps the objects in the solar system such as planets orbiting around the sun the force of gravity the galaxy exerts on all objects within it including the solar system the great distance between the sun and the planets the sun's nuclear fusion which acts on each object the gravitational force between the sun and each object in the solar system
