An airplane flies eastward and accelerates uniformly. At one position along its path it has a velocity of 33.5 m/s. It then flies a further distance of 46.9 km and its velocity is 43.1 m/s. Find the airplane's acceleration and calculate how much time elapses while the airplane covers those 46.9 km.
Two boats start together and race across a 62-km-wide lake and back. Boat A goes across at 62 km/h and returns at 62 km/h. Boat B goes across at 31 km/h, and its crew, realizing how far behind it is getting, returns at 93 km/h.
A 30-06 bullet has a mass of 0.010 kg. If the average force on the bullet is 7200 N, what is the bullet's average acceleration?
how is the graph of the total volume of a bathtub while the water inflow rate follows a seesaw pattern for half of the time and the similar pattern for outflows on the other half.
An electric field of intensity 2.5 kN/C is applied along the x-axis. Calculate the electric flux through a rectangular plane 0.350 m wide and 0.70 m long if the following conditions are true.
If the aspirin could be converted completely into thermal energy, how many miles will the car go on a single tablet.
Two identical positive charges exert a repulsive force of 6.2 multiplied by 10-9 N when separated by a distance of 3.4 multiplied by 10-10 m. Calculate the charge of each.
At t=0 a grinding wheel has an angular velocity of 30.0 rad/s. It has a constant angular acceleration of 31.0 rad/s^2 until a circuit breaker trips at time t = 2.00 s. From then on, it turns through an angle 428 rad as it coasts to a stop at constant..
A group of hikers hears an echo 3 s after shouting. If temperature is 16°C, how far away is the mountain that reflected sound wave.
A stone is dropped at t = 0. A second stone, with 2 times the mass of the first, is dropped from same point at t = 190 ms. (a) How far below the release point is the center of mass of two stones at t = 390 ms? (Neither stone has yet reached the gr..
A particle with a charge of q = -5.00 nC is moving in the uniform magnetic field of vec{B}=( -1.20 T ) hat{z}. The magnetic force on the particle is measured to be vec{F}= ( -7.60×10-7 N )hat{y}.
Assume that plane continues to fly with the similar velocity
A banked circular highway curve is designed for traffic moving at 85 km/h. The radius of the curve is 158 m. Traffic is moving along highway at 48 km/h on the rainy day. What is the minimum coefficient of friction between tires and road that would al..
