11. A sled at Canada Olympic Park in Calgary has a mass of 25.0 kg. A rider with a mass of 78.0 kg begins the run by pushing the sled to a speed of 1.20 m/s. By the time the sled gets to the first turn in the track, it has gained 2.25 x 10° J of kinetic energy. At that time, what is the speed of the combined mass?

Consider the table. Vehicle 1 Vehicle 2 Vehicle 3 Vehicle 4 Mass (kg) 1000 2000 1000 2000 Velocity (m/s) 20 20 40 40 Kinetic energy (kJ) 200 400 800 1600 The table shows data collected for some vehicles on the road. What conclusion can be drawn about the relationship between mass, velocity, and kinetic energy? Answer Choices: a. If only the mass of the vehicle doubles, the kinetic energy increases by a factor of four. b. If both the mass and the velocity of the vehicle double, the kinetic energy will increase by a factor of eight. c. If only the velocity of the vehicle doubles, the kinetic energy will double. d. If both the mass and the velocity of the vehicle double, the kinetic energy will increase by a factor of four.
A particle of mass m = 1.50 kg moves along one dimension and is subject to a single force, whose potential energy function is given by U(x) = x4 – 2x2 + 4 (where U is measured in Joules and x is measured in meters). At the moment when the particle is located at position x = 1.50 m, its speed is v = 2.50 m/s. %3D
