(b) A frictionless incline is 5.00 m long (the distance from the top of the incline to the bottom, measured along the incline). The vertical distance from the top of the incline to the bottom is
1.66 m. A small block is released from rest at the top of the incline and slides down the incline.
(i) How long does it take the block to reach the ground?
3.25 s
(ii) What is the speed of the block just before it strikes the ground?
1.75 m/s
(a) A car of mass m is on an icy driveway inclined at an angle ϴ=20°, as in
Figure below. Determine the acceleration of the car, assuming the incline is
frictionless. (b) If the length of the driveway is 25m and the car starts from
rest at the top, how long ( ) does it take to travel to the bottom? (c) What is
the car’s speed at the bottom?
