A bowling ball of mass 2.0 kg strikes a stationary pin of mass 5.00 x 102 g. The collision lasts for 0.60 s after which the pin moves off with a velocity of 12.0 m/s [W]. Determine the acceleration of the bowling ball during the collision.
A speedboat starts from rest and accelerates at+1.91 m/s2 for 7.00 s. At the end of this time, the boat continues for an additional 6.00 s with an acceleration of+0.518 m/s2.
An open-open organ pipe is 84.2 cm long. An open-closed pipe has a fundamental frequency equal to the third harmonic of the open-open pipe. How long is the open-closed pipe
A wire of thickness d = 1.9 mm is tightly wound in a single layer 200 times around a cylindrical core to form a solenoid (no space between its turns). evaluate the magnetic field at the center of the solenoid
The equation F = arv + br2v2 gives the magnitude of the resistive force (in newtons) exerted on a sphere of radius r (in meters) by a stream of air moving at speed v (in meters per second), where a and b are constants with appropriate SI units.
A cricket bowler can bowl a 158 g ball at 147 km/hr. Calculate the kinetic energy of this bowl and use this to compare to a bowling ball that weighs 7 kg. How fast would the bowling ball need to be bowled to have the same kinetic energy as the cri..
