Question

One game at the amusement park has you push a puck up a long, frictionless ramp. You win a stuffed animal if the puck, at its highest point, comes to within 10 cm of the end of the ramp without going off. You give the puck a push, releasing it with a speed of 5.0 m/s when it is 8.50 m from the end of the ramp. The puck's speed after traveling 3.0 m is 4.0 m/s.

Answer 1

Step-by-step explanation:

Given

initial speed(u)=5 m/s

Final speed(v)=4 m/s

Distance traveled=3 m

using equation of motion

`v^2-u^2=2as`

`4^2-5^2=2(a)(3)`

`a=(-3)/(2)=-1.5 m/s^2`

after this its final velocity will be zero

`v^2-u^2=2as`

`0^2-4^2=2* (-1.5)* s`

s=5.33 m

Total distance=3+5.33=8.33 m

Thus he will not be able to win the game
