When a car moving with `36 km h^(-1)` reaches an upward inclined road of angle `30^@` ,its engine is switched off.If the co-efficient of friction is 0.1,how much distance will the car move before coming to rest ?(Take `= 10 m s^(-2)`).

A particle of mass 10^-3 kg and charge 5 muC is thrown at a speed 20 ms^-1 against a uniform electric field of strength 2xx 10^5 NC^-1 , How much distance will it travel before coming to rest momentarily?

An inclined plane making an angle of 30^@ with the horizontal is placed in a uniform horizontal electric of 100 V m^-1 as shown in the figure A particle of mass 1 kg and charge 0.01 C is allowed to slide down from rest from a height of 1 m. If the coefficient of frictio nis 0.2, find the time it will take the particle to reach the bottom.

A car is moving with a speed of 30 m s^(-1) on a cricular path of radius 500 m.Its linear speed is increasing at the rate of 2 m s^(-2) .Find the values of its net acceleration.

A body of mass 2 kg initially at rest moves under the action of an applied horizontal force of 7 N on a table with coefficient of kinetic friction = 0.1. Compute the:- work done by the applied force in 10 s.

A body of mass 2 kg initially at rest moves under the action of an applied horizontal force of 7 N on a table with coefficient of kinetic friction = 0.1. Compute the:- work done by the net force on the body in 10 s.

A particle of mass 150 g is attached to one end of a massless inextensible string It is made to describe a vertical circle of radius 1 m When the string is making an angle of 48.2^(@) with the vertical , its instantaneous speed is 2 m//s What is the tension in the string in this position ? Would this particle be able to complte its circular path?(Take g=10 m s^(-2) ).

On a two-lane road, car A is travelling with a speed of 36 km h^-1 . Two cars B and C approach car A in opposite directions with a speed of 54 km h^-1 each. At a certain instant, when the distance AB is equal to AC, both being 1 km, B decides to overtake A before C does. What minimum acceleration of car B is required to avoid an accident ?
