A cannon sends a projectile towards a target a distance 1440 m away. The initial velocity makes an angle 23◦ with the horizontal. The target is hit. The acceleration of gravity is 9.8 m/s2 . What...

A plane drops a hamper of medical supplies from a height of 3080 m during a practice run over the ocean. The plane’s horizontal velocity was 135 m/s at the instant the hamper was dropped...

Bullet wait is 0.05 kg penetrates into a block of food of mass 2 kg velocity of 150 M per second hand gets embedded in the block of wood if the block of wood was initially at rest calculate the work...

Two parallel train tracks runs from north to south .one track train A is moving from north to south with speed of 54 km per hour on the other track train B is moving South to North with speed of 90...

The total distance traveled by a ball launched at an angle of 15 degrees is approximately 1.38 meters. Not counting air friction, and the final velocity being zero, how would you find the velocity...

A plane has a velocity of 300 km/h relative to the air. If the pilot points the plane straight north, when there is a wind of 80 km/h blowing towards the west, what will the resulting velocity be...

The power developed by a certain engine is a function of time according to P = 2 + 3t2 + 4t3 where the units are SI. The work done by the engine in the interval from...

In magazine car tests an important indicator of performance is the zero to 65 mph (0 to 104.6 km/h) acceleration time. A time below 6 s is considered to be extremely quick. If a car with mass 1300...

A proud new Jaguar owner drives her car at a speed of 35 m/s into a corner. The coefficients of friction between the road and the tires are 0.70 (static) and 0.40 (kinetic). What is the minimum radius...

A tired worker pushes a heavy (100-kg) crate that is resting on a thick pile carpet. The coefficients of static and kinetic friction are 0.6 and 0.4, respectively. The worker pushes with a force of...

A 50-kg box is placed in the bed of a truck. The coefficient of static friction between the box and the truck bed is 0.54. If the truck is traveling at 100 km/h then calculate the minimum distance...
