Answer:

Explanation:

Work is a force time the distance moved in the direction of that force, time is not a variable. Provided that the 50 N forces were applied in the same direction, the work done is identical. Assuming both applied force and direction of motion are horizontal W = Fd = 50(10) = 500J.

If the reason that one was slower is because the  second person applied his force at an angle, let's say 60° below the horizontal, then the work done by the second person is 50cos60(10) = 250 J

Time IS a consideration for Power, the RATE of doing work. Provided the force and motion are horizontal, the first person applied twice as much Power as the second person doing an identical amount of work in half the time.

Calculate the change in momentum of a 45 kg runner who starts out at 1 m/s and speeds up to 3 m/s. Which anser choice is correct
Step2247 [10]

momentum can also be defined in terms of newton second

that is P=F.V

now v =vf-vi

v=3 m/s-1m/s=2 m/s

now F=W=45 kg

therefore

change in momentum=F.v

P=45*2=90 kg.m/s

A car, a bicycle, a bus, and a motorcycle are moving parallel to each other on a road. Each vehicle is traveling at the same spe
Olin [163]
The BUS will have the highest kinetic energy, while the BICYCLE will have the lowest kinetic energy.

This is because if an object has a greater mass, the kinetic energy of the object also increases. Kinetic energy depends on mass and velocity (KE=1/2*m*v^2) and since the velocity of these vehicles are the same, the mass is the only difference
