A skier starts from rest and accelerates down a slope at 2.3 m/s^2. How much time is required for the skier to reach a speed
of 4.9 m/s?

Acar travels 40m in 8 seconds find the car speed

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)

What is the relationship between wavelength of light and the quantity of energy per photon?
