Question

Two pulses on a string are sent toward each other from opposite ends of the string as shown. Which of the pictures below could NEVER result from this situation? A plane 5 meters in length is inclined at an angle of 37 degree, as shown above. A block of weight 20 newtons is placed at the top of the plane and allowed to slide down. The mass of the block is most nearly A cart of mass 5.0 kilograms is moving horizontally in a straight line at 6.0 meters per second. In order to change its speed to 10.0 meters per second, the work done on the cart must be

Explanation / Answer

1) d

2) e) 2.0 kg

m = W/g = 20/9.8 = 2.04 kg

3) a) 160 J

workdone, W = change in kinetic energy

= 0.5*m*(vf^2 - vi^2)

= 0.5*5*(10^2 - 6^2)

= 160 J
