suppose both the dog and the girl run at a speed of 2 m/s. Calculate both of there kinetic energies. kinetic energy of dog =

Abody of weight 60 kg is standing in a lift the lift going upward with a uniform velocity of 4.9 metre per second slows down and stops in two seconds then apparent weight of the body during the slow down process is

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.

You pump 25.0l of air at atmospheric pressure into a soccer ball that has a volume of 4.50l. what is the pressure inside the soccer ball if the temperature does not change?
