A four wheel drive with a mass of 2.461 tonnes is being winched up a ramp 13m in length with a gradient of 1 in 3. If the rolling resistance between the ramp and the vehicle is 124N Determine: a) The potential energy gained by the vehicle moving between the bottom and top of the ramp. b) The force required to pull the vehicle up the ramp. d) c) The work done pulling the vehicle from the bottom to the top of the ramp. If the vehicle breaks free just as it reaches the top of the ramp and rolls backwards, calculate the speed in kmh as it reaches the bottom of the ramp. If the vehicle continues to roll along the flat, how far will it travel assuming the rolling resistance is the only braking force with a value of 540N. e) A four wheel drive with a mass of 2.461 tonnes is being winched up a ramp 13m in length with a gradient of 1 in 3.
