A wheelchair ramp is 5.2 m long and 0.8 m high. Calculate the ramp's mechanical advantage O A 6.5
OB. 5.2
O C. 4.2
O D. 4.4

What object a collides with object b and bounces back its final momentum is?

Gordon is going for a run through the park, but it is cold outside. the low outside temperature could affect his personal safety.

Refer to your lab guide and review the data in table b to complete each statement. the mass of g1 + g2 after the collision kg. the velocity of g1 + g2 after the collision m/s. the momentum of the combined gliders after the collision kg · m/s.
