A missile is fired from a launcher with an initial velocity of 250 m/s at a target located 500 m above the launcher and at a horizontal distance of 3000 m. Determine the following:
i) The possible firing angles required to hit the target.
ii) The maximum height reached for all possible angles.
iii) The time taken for the missile to hit the target for all possible firing angles.
Find the current in a 11.00 ? resistor connected to a battery that has an internal resistance of 0.25 ? if the voltage across the battery (the terminal voltage) is 24.00 V
Two carts with masses of 5.00 kg and 2.64 kg move toward each other on a frictionless track with speeds of 4.86 m/s and 3.46 m/s correspondingly. The carts stick together after colliding head-on. Find the final speed.
A spool of thin wire rotates without friction about its axis. A man pulls down on a wire connected to an inner radius with force of 16.10 N. How long does it take to enlarge the angular velocity of the spool from 11.00 rad/s to 39.00 rad/s? Icm = ..
Find out the acceleration of the sled and child
A 70Kg diver steps off a 10 m tower and drops from rest straight down into the water. If he comes to rest 5.0 m beneath the surface, decide average resistive force exerted on him by the water.
The density of bcc iron is 7900 kg/m3 and its atomic weight is 56. Calculate the side of the cubic unit cell and the interatomic spacing
A liquid is flowing through a horizontal pipe whose radius is 0.0216 m. What volume flow rate will keep the pressures in the two horizontal pipes the same
At the instant the car begins to accelerate, a truck with a constant velocity of 21 m/s passes in the next lane. Explain how far will the car travel before it overtakes the truck?
A child goes down a playground slide with an acceleration of 1.34 m/s2. Compute the coefficient of kinetic friction between the child and the slide if the slide is inclined at an angle of 34.0° below the horizontal.
A wooden block of mass M = 0.170 kg is placed on a wooden inclined board 0.930 m long and raised to a height h1 = 0.050 m at the lower end, calculate the work done on the block by the normal force
An atomic nucleus of mass m travelling with speed v collides elastically with a target particle of mass 2.000m (at first at rest) and is scattered at 90.
A turbine that uses steam drives an electric generator. The inlet stream flows through a 10 cm diameter pipe to the turbine at 2.5 kg/s at 600°C and 1000 kPa. The exit steam discharges through at 25 cm diameter pipe at 400°C
