Work is a dot product of the force and displacement, so W = (x component of the force) x d = 400 N x 7 m = 2800 J = 2.8 kJ.

Just calculate the individual distances and sum them for the total distance: d = 45/60 * 55 + 16/60 * 95 + 55/60 * 50 km Then calculate the total time t (3 trip times plus 30 min). Average speed = d/t

Speed vertically of 24m/sec will take a height of (v^2/2g) = 29.388 metres to attain. The v^2 is 24^2, not 15^2, and g used is 9.8.

You know the linear speed and the mass of the ball so you know the translational kinetic energy, Kt Kt = 1/2 mv^2 = 50.54 J Now to get he rotational energy Kr, you need the moment of inertia of a solid sphere taken aroun its center, and the rotational speed of the ball...

For a solid sphere, I = (2/5)mr² and rotational KE = ½Iω² = ½ * (2/5)mr² * (v/r)² = (1/5)mv² So: translational KE = ½ * 7.1kg * (4.6m/s)² = 75 J rotational KE = (1/5...

Note that, after t seconds, the boat travels 1.65t m towards the short and the boat floats 1.05t m down stream. Then, the distance that the boat actually travels is: D = √[(1.65t)^2 + (1.05t)^2] = 1.96t. Therefore, the
