An object is thrown downward with an initial speed of 7 m/s from a height of 95 m above
the ground. At the same instant, a second
object is propelled vertically up from ground
level with a speed of 44 m/s.
At what height above the ground will the
two objects pass each other? The acceleration
of gravity is 9.8 m/s
2
.
Answer in units of m.

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]
