Really need help with this asap plz~
there is a 4kg wooden block on top of a wooden ramp forming an angle of 37 degrees above surface.The block is placed 1.2 m up on the ramp and the ramp is connected to another wooden flat board.So when the block slides down, it continues a smooth motion across the wooden surface. The question is then asking how far does the block travel before it comes to a stop.

1. assuming No friction, it travels forever and ever. Only friction can slow it down, or stop it.

I strongly suspect you were given information about the coefficent of friction.

2. Denise is conducting a physics experiment to measure the acceleration of a falling object when it slows down and comes to a stop. She drops a wooden block with a mass of 0.5 kilograms on a sensor on the floor. The sensor measures the force of the impact as 4.9 newtons. What’s the acceleration of the wooden block when it hits the sensor? Use F = ma.
