Question

A toy car, with mass m = 200 g is given a velocity of 10 m s at the top of the first hill with height h = 1 m. The toy car goes down the hill to the ground and starts up the second hill of height h = 2 m. At the top of the hill is a spring, with spring constant k = 100 N C . How far does the spring compress when the car gets to the top of the hill?

Four asteroids, of mass M = 3 × 106 kg, are positioned at the corners of an imaginary square of side length s = 2.4 × 108 m. Two other asteroids of mass m = 2 × 106 kg are positioned in the middle of the left and right sides of the square. If a spaceship is positioned at the middle of the bottom side of the square what is the net force on the ship in Newtons?

Answer 1

Note : Mass of spaceship is not given in the question therefore you can't find the numerical value of the force acting on the spaceship.

In my calculations i have written the expression for the net force. Put the mass respective values and get the numerical answer.

Thankyou
