You toss a ball into the air at an angle 40 ∘
from the horizontal. At what point in the ball's trajectory does the ball have the smallest speed? (Neglect the effects due to air resistance) halfway between the ground and the highest point on the fall of the trajectory just before it hits the ground halfway between the ground and the highest point on the rise of the trajectory just after it is tossed at the highest point in its flight A block is sliding down the ramp. How does the magnitude of the normal force exerted by the ramp compare to the weight of the block? The normal force is possibly greater than or equal to the weight of the block, depending on whether or not the ramp surface is smooth. less than the weight of the block. possibly equal to or less than the weight of the block, depending on whether or not the ramp surface is smooth equal to the weight of the block. greater than the weight of the block. Bob and Lily are riding on a merry-go-round. Bob rides on a horse toward the outer edge of a circular platform and Lily rides on a horse toward the center of the circular platform. When the merry-goround is rotating at a constant angular speed w, Bob's speed v is larger than Lily's exactly half as much as Lily's smaller than Lily's. the same as Lily's. exactly twice as much as Lily's
