An electric vehicle starts from rest and accelerates at a rate of 2.0 m/s2 in a straight line until it reaches a speed of 20 m/s. the vehicle then slows at a constant rate of 1.0 m/s2 until it stops. (a) how much time elapses from start to stop? (b) how far does the vehicle travel from start to stop?

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?

Heating water for hot cocoa while sitting next to a campfire can be examples of conduction, convenction and radiation at the same time agree disagree it depends how you know

Acar going 30 m/s to 70 m/s in 10 seconds calculate the acceleration of the car
