A block of mass M is slides with an initial speed v along a horizontal surface with negligible friction. A constant force of magnitude F is exerted on the object at an upward angle of 60 degrees from the horizontal, causing the object to speed up. If the block remains in contact with the floor, what is the change in the block’s kinetic energy as it moves a horizontal displacement, d? ( textbook question page 225) 1/2fd Fd Fd/m 2Fd

Express your answer in meters, to at least one digit after the decimal point. plz help and use g = 9.8
A student, starting from rest, slides down a water slide. On the way down, a kinetic frictional force (a nonconservative force) acts on her. The student has a mass of 81 kg, and the height of the water slide is 11.8 m. If the kinetic frictional force does -5.1 × 103 J of work, how fast is the student going at the bottom of the slide?

As usual, Hampus is out cycling. He is driving at 30.0 km/ h when he comes to a small hill that is 11 m high and 350 m long. Hampus and the bike weigh 95 kg together. a) What kinetic energy does Hampus have just before the hill? b) How much extra energy must Hampus produce to maintain a constant speed (30.0 km/ h) throughout the hill? c) How long does it take him to drive up the hill? d) What effect must he develop on the hill? Once at the top of the hill, the ground is flat. Hampus is tired and stops pedaling. After 12s the cycle stops. e) How big is the coefficient of friction? You can assume that is constant throughout the deceleration and that it includes both drag and rolling resistance.
