A boy pulls his toy on a smooth horizontal surface with a rope inclined at 60 degrees to the horizontal. If the effective force pulling the toy along the horizontal surface is 5N, calculate the tension in the rope

The tendency of an object to resist a change in its motion

If a tennis player's arm muscles are weak and unable to produce enough force with one hand to accelerate the ball sufficiently, he can create more total force by hitting with two hands.

How would local winds be affected if water and land release heat at the same time

Suppose you made some beef soup. you want to separate the extra fat from the soup before you eat it. how could you do that?

How does temperature change affect surface tension

How do you find period when you have frequency

Calculate the speed for a car that went a distance of 125 miles in 2 hours time

A small 25 kilogram canoe is floating downriver at a speed of 4 m/s. What is the canoe's kinetic energy?

A car traveling on a flat (unbanked), circular track accelerates uniformly from rest with a tangential acceleration of 1.85 m/s2. The car makes it one quarter of the way around the circle before it skids off the track.
