The driver of a car travelling at 2m/s hits the brakes which provides a steady deceleration of 3m/s2 , how far does the vehicle travel before coming to rest?

A stone is thrown into a well 6m deep. The stone is thrown from rest. How

long will it take before you hear the stone hit the floor of the well. Assume

speed of sound is 2m/s (this is not the actual speed of sound, please!!)?

A car is preceding down a 1 in 10 incline at 65KPH when it's brake are abruptly applied. How far does it skid along the road before stopping if the wheels lock and the coefficient of friction between the tyres and the road is 0.7 ?

A stone is thrown into the air with initial speed of 3m/s from the ground.

What time does it hit the ground? (Neglect air resistance)

What happens when a long, straight conductor is moved through a uniform magnetic field at constant velocity? Assume that the conductor moves perpendicular to the field.

A -6 nC particle is moving at 4.0x10^4m/s along the positive z-axis.It passes a region undeflected where there is uniform electric and magnetic fields.The electric field is 5.75 x10^5 N/C along the negative x-axis.What is the magnitude and direction of the magnetic field.
