A warship has a gun that fires a projectile at an initial speed of 400 m/s. It fires at an enemy ship that is 10.0 km away. At what angle from the horizontal should the gun be fired in order to hit the enemy, assuming that the enemy’s location does not change? (Hint: you can write two equations involving time, one for the horizontal motion, and one for the vertical motion. Solve one equation for time and substitute into the...

Pictured below is a model for a train that is traveling at the steady speed of 50 m/s through standard air at sea level. The cross section of the train will be modeled as a semicircle so that the train itself is half of a circular cylinder. Neglect the effects of any airflow beneath the train. The engine car drives the train with a propulsive thrust, and there is a coupling connecting the engine car to the passenger car. Assume...

Problem A car travels at a constant speed of 29.5 mi/h (13.2 m/s) on a level circular turn of radius 46.0 m, as shown in the bird's-eye view in Figure 7.13a. What minimum coefficient of static friction, Aus, between the tires and the roadway will allow the car to make the circular turn without sliding? Strategy In the car's free-body diagram (Fig. 7.13b) the normal direction is vertical and the tangential direction is into the page (step 2). Use Newton's...

I am pushing a shopping cart, causing it to accelerate at a rate of 0.18 m/s2. I would like to double my rate of acceleration. How much harder must I push? I am pushing a shopping cart, causing it to accelerate at a rate of 0.16 m/s2. If this shopping cart had more groceries in it, causing it to be twice as massive, how much more would it accelerate? A 9.8 kg object is moving at a constant speed of...

2. Suppose a car travels 108 km at a speed of 20.0 m/s, and uses
2.20 gallons of gasoline. Only 30% of the gasoline goes into useful
work by the force that keeps the car moving at constant speed
despite friction. (The energy content of gasoline is 1.3 ✕
108 J per gallon.)
(a) What is the force exerted to keep the car moving at constant
speed?
N
(b) If the required force is directly proportional to speed, how
many...
