If the coefficient of friction for a drag racer's tires on concrete is 1.2 and the drag racer weighs 10,000 N, how much friction force pushes the care forward?

How will the system respond to a temperature increase?

If the textbook weighs 19.6 newtons on venus,what is the strength of gravity on venus?

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
