1.3. A vehicle of mass 3000 kg is travelling at 55 km/h. a. Calculate the kinetic energy of the vehicle. b. How far would the vehicle travel on a level road against a frictional resistance of 1.2 kN? c. In addition to the frictional resistance, a braking force of 1.5 kN is applied. Recalculate the distance travelled.
A sledgehammer is used to do sugenammer is used to drive a stake into the ground as shown below. The sledgehammer has a 0.00 kg and the stake has a mass of 10.0 kg. The sledgehammer falls from a distance or 0.700 m and drives the stake 225 mm into the ground. Assume that the sledgehammer remains in contact with the stake and does not bounce. Resisting force Hammer Stake 2.1 Determine the retarding force in the ground using the conservation of energy principles.
