Q. A 25g ball is fired with an initial speed v1 toward a 150g ball that is hanging motionless from a 1.30m string. The balls have a perfectly elastic collision. As a result, 150 g ball swings out until the string makes an angle of 37° with vertical. What was v1?
Q. A fighter pilot flying with a speed of 500•m/s (about Mach 1.5) makes a turn with a radius of 5250•m. What centripetal acceleration does pilot experience? Express your answer in g's (multiples of 10•m/s2).
At rest, a car's horn sounds at a frequency of 385 Hz. The horn is sounded while the car is moving down the street. A bicyclist moving in the similar direction with one-third the car's speed hears a frequency of 342 Hz. What is the speed of the ca..
Find out the speed of a 56.7 kg thrill seeker at the bottom of the slide, assume no friction. If the thrill seeker has a speed of 24.1 m/s at the bottom, find out the change in mechanical energy due to friction.
A 150g ball and a 250g ball are connected by a 34cm long, massless, rigid rod. The balls rotate about their center of mass at 130 . what is the speed of ball of 150 g.
What is the total charge on Earth's surface implied. explain the strength and direction of an electric field.
Suppose an initial speed of 21.4 m/s, at an angle of 61.10° with respect to the positive x axis. Find the velocity at time t0; enter x component, after that the y component.
If frame rate increases what happens to the PRF
The 3.3 kg piece of wood slides on the surface. The curved sides are perfectly smooth, but the rough horizontal bottom is 35 m long and has the kinetic friction coefficient of 0.24 with the wood. The piece of wood starts from rest 6.0 m above the rou..
An airplane must reach a speed of 186mi/h to take off. If the runway is 488m long, what is the minimum value of acceleration that will allow the airplane to take off successfully.
A radio station broadcasts at a frequency of 600,000 Hz. Know that radio waves have a speed of 3.00 x 10^8m/s, what is wavelength of these waves.
A sound wave traveling at 341m/s is emitted by foghorn of a tugboat. An echo is heard 3.30s later.
Imagine that plane reaches the necessary takeoff velocity
A 6.4g lead bullet traveling at 460m/s is stopped by a large tree. If half the kinetic energy of the bullet is transformed into internal energy and remains with the bullet while the other half is transmitted to the tree, what is the increase in te..
