A golfer strikes a golf ball with an initial velocity of 40.0m/s at an angle of 37.5 degrees above the horizontal. Solve for the horizontal component of the ball's velocity.

Which type of microscope would allow the viewer to see ribosomes inside a cell?

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
