A car speeds past a stationary police officer while travelling 115km/h. The officer immediately begins pursuit at a constant acceleration of 10.20 km/h/s (note the mixed units), just as the driver passes the officer.
Assume that the masses of the chains, pulleys, and ropes are negligible and the crate is rising with an acceleration of 2.9 m/s2. Determine the force also examine the tension in the upper chain.
What is the wavelength of the waves emitted by source? What is the difference in frequency between directly radiated waves and the waves reflected from a whale travelling straight toward the ship at 4.99? Suppose that the ship is at rest in the water..
An electric vehicle starts from rest and accelerates at a rate of 1.7 m/s2 in a straight line until it reaches a speed of 27 m/s. The vehicle then slows at a constant rate of 1.0 m/s2 until it stops. (a) How much time elapses from start to stop? (..
A dock worker applies a stable horizontal force of 79.0 {rm N} to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts from rest and moves 14.0 {rm m} in the first 6.00 {rm s}.What is the mass of the bl..
