a jet fighter plane is launched from a catapult on an aircraft carrier, it reaches a speed of 42m/s at the end of the catapult and this requires 2.0s assuming the acceleration is constant what is the length of the catapult

Atrain departs from its station at a constant acceleration of 5 m/s. what is the speed of the train at the end of 20s?

Free runners jump long distances and land on the ground or a wall. how do they apply newton’s second law to lessen the force of impact?

The magnetic field inside a superconducting solenoid is 4.50 t. the solenoid has an inner diameter of 6.20 cm and a length of 26.0 cm. determine (a) the magnetic energy density in the field and (b) the energy stored in the magnetic field within the solenoid.
