A second baseman tosses the ball to the first baseman, who catches it at the same level from which it was thrown. The throw is made with an initial speed of 16.0m/s at an angle of 32.5? above the horizontal. Let upward be the positive y direction.
Part A What is the y component of the ball's velocity?
Part B What is the ball's direction of motion just before it is caught?
find the magnitude and direction of the resultant force A + B that is applied to the stump. Specify the direction with respect to due east.
Two masses, m1= 3.32 kg and m2= 5.00 kg are on a horizontal frictionless surface and they are connected together with a rope, What is the acceleration of the whole system, when this maximum force is appiled
Two runners of mass 70kg and 60kg, respectively, have a total linear momentum of 350 kg•m/s. The heavier runner is running at 2.0 m/s. Determine the likely speeds of the lighter runner.
A 2.20 kg frictionless block is attached to an ideal spring with forces constant 314N/m. At first the block has velocity -3.60 m/s and displacement 0.300-m.
A circuit contains six 205 ohm lamps with 60 W bulbs and a 9 ohm heater connected in parallel. voltage across the circuit is 120 V.what is the current in the circuit when four lamps are turned on.
A string passes over a frictionless pulley and connects a 250 g block to 2.00 kg block. The inclines are frictionless. Assuming you release both masses from rest, how much time would it take the 250g to travel 2200cm next to the ramp.
What is the friction force that acts on the bear?
A 200g block is suspended from a vertical spring, causing the spring to strech by 20 cm, What is the speed of the block when it is 5.0cm above the equilibrium position
If John Glenn weighed 640 N on the Earth's surface, i) how much would be having weighed if his Mercury spacecraft had (hypothetically) remained at twice the distance from the center of the earth? ii) Why is it said that an astronaut is never truly..
The coefficient of friction between his clothes and Earth is 0.70. He slides so that his speed is zero just as he reaches the base. Evaluate how far does he slide?
Because the mass would not make it around the loop if released from the height of the top of the loop (do you know why?) it should be released above the top of the loop-the-loop height.
The mass of a robot is 5220 kg. This robot weighs 2650 N more on planet A than it does on planet B. Both planets have the same radius of 2.26 × 107 m
