A car is traveling on a straight level track with a uniform speed of 25 m/s. When the car is moving away from a gun at the same level at a distance of 1500 m the gun is fired at an angle of `45^(@)`. Find the distance of the car (kilometers) from the gun when it is hit.

A car moving aling a straight highway with speed of 126 km h^(-1) is brought to a stop within a distance of 200 m . What is the retardation of the car (assumed uniform ) ans how doest it take fro the car to stop ?

A car is moving with at a constant speed of 60 km h^(-1) on a straight road. Looking at the rear view mirror, the driver finds that the car following him is at a distance of 100 m and is approaching with a speed of 5 km h^(-1) . In order to keep track of the car in the rear, the driver begins to glance alternatively at the rear and side mirror of his car after every 2 s till the other car overtakes. If the two cars were maintaining their speeds, which of the following statement (s) is // are correct?

A driver travelling at speed 36 kmh^(-1) sees the light trun red at the intersection. If his reaction time is 0.6s, and then the car can deaccelerate at 4 ms^(-2) . Find the stopping distance of the car.

A car moving along a straight highway with speed of 126 km h^(-1) is brought to a stop within a distance of 200 m. What is the retardation of the car (assumed uniform), and how long does it take for the car to stop ?

A car moving over a straight path, covers a distance d with constant speed of 40 km/hr and then the same distance with speed 60km/hr. The average speed of car is .....

A straight highway leads to the foot of a tower. A man standing at the top of the tower observes a car at an angle of depression of 30^(@) , which is approaching the foot of the tower with a uniform speed. Six seconds later, the angle of depression of the car is found to be 60^(@) . FInd the time taken by the car to reach the foot of the tower from this point.

A pendulum is suspended from the roof of a rall road car. When the car is moving on a circular track the pandulum inclines:

In the figure there is a long horizontal bridge over a river 75 m high from water surface. A strong man throws a stone in the parallel plane of the bridge. A observer in a car travelling on the bridge finds the stone going pass by the car while ascending and also while descending between two points on the road 30 m away. The car is travelling at a speed of 15 m/s. The stone is thrown from the bank of river just at the same level of water. What is the distance between car and atone at the instant when particle reaches at point B ?

A tank is initially at a perpendicular distance BT=360 m from the plane of firing as shown . The enemy tank is moving with a speed of 9 m/s in direction TA as shown in figure. A gun can fire shell in y-z plane only with a speed 100 m/s at an angle of 53^(@) such that the shell lands at points A. If tank started at t=0 then time interval (in sec) after which shell is to to be fired to hit the tank is

A particle moving in a straight line covers half the distance with speed of 3 m//s . The half of the distance is covered in two equal intervals with speed of 4.5 m//s and 7.5 m//s respectively. The average speed of the particle during this motion is :
