A baseball thrown at an angle of 55.0?^\circ above the horizontal strikes a building 16.0m{\rm m} away at a point 7.00m{\rm m} above the point from which it is thrown. Ignore air resistance.
Part A: find the magnitude of the initial velocity of the baseball (the velocity with which the baseball is thrown)
Part B: find the magnitude of the velocity of the baseball just before it strikes the building
Part C: Find the direction of the velocity of the baseball just before it strikes the building
If the velocity of the car is increased to 50 km/ hour, what is its kinetic energy. if the velocity is improved to 75 km/ hour, what is its kinetic energy.
A speedboat moving at 30 m/s approaches a no-wake buoy marker 100 m ahead. The pilot slows the boat with a constant acceleration of negative 3.5 m/s^2 by reducing the throttle. How long does it take boat to reach the buoy.
Using the data calculate the average speed of blood flow in the major arteries of the body which have a total cross-sectional area of about 2.0 cm2.
Does papillary muscles contract after the other ventricular muscles so that they can take up the slack on the chordae tendineae before the full force of ventricular contractions sends blood against the AV valve flaps.
A car is being pulled out of the mud by two forces that are applied by the two ropes. The dashed line in the drawing bisects the 30.0° angle.
A 18 liter tank of helium is at a pressure of 192 kPa at a temperature of 0 C. A.) How many moles of helium are there in the tank? B.) If the volume of the tank expands to twice its initial volume at constant pressure, what is the new temperature?..
Two particles are fixed on x-axis. Particle 1 of charge q1 = -2×10^-7 C at x = 20 cm and particle 2 of charge q2 = +8×10^-7 C at x = 70 cm. At what x coordinate on the axis is net electric field produced by the particles equal to zero.
An automobile club plans to race a 780 kg car at the local racetrack. The car needs to be able to travel around several 170 m radius curves at 85 km/h. What must the banking angle of the curves be so that the force of the pavement on the tires of the..
A wave has a speed of 500.0 m/s and a wavelength of 4.9 m. What is the frequency of the wave? What is the period of the wave?
A ship sets out to sail to a point 141km due north. An unexpected storm blows the ship to a point 138 km due east of its starting point. (a) How far (in km) and (b) in what direction (as an angle from due east, where north of east is a positive an..
