A mass that is significantly larger than another. The larger mass hits the stationary smaller mass. I don't understand why the smaller mass has a velocity of 2 times the larger mass after the collision. Does it have something to do with v1(initial) - v1(final) = v2(initial) - v2(final)?

Homework Statement A golf ball is hit from the freeway at a speed of 40 m/s and an angle of 45 degrees. Upon hitting the ground the ball bounces off the ground at the same angle but loses 75% of its speed on each bounce. How far does the ball travel before stopping? Homework Equations...

When a golf ball goes round the hole and doesn't drop (bit like an orbit), it often appears to leave the hole faster than it went in. My understanding of physics tell me that this is not possible, as any speed gained from gravity when it dips slightly into the hole, is lost when it gains height...

Hi, I'm trying to design a solution to the problem of finding golf balls in the rough. I've had a few thoughts so far: - Image processing to detect white objects in a predominantly green environment - UV light emitter and detector to take advantage of fluoresence of the whitening coating of...

A golf ball without dimples experiences more drag because the deflection area of the airflow around the ball is larger which means that the pressure drop behind the golf ball is also higher. The increased drop in pressure creates a suction vacuum behind the golf ball which pulls it back and...

Homework Statement In a typical tee shot, a golf ball is hit by the 300 g head of a club moving at a speed of 40 m/s. The collision with the ball happens so fast that the collision can be treated as the collision of a 300 g mass with a stationary ball—the shaft of the club and the golfer can...

A and B play a game of golf ( where the player with the lowest score wins). The deck is divided so that 17 cards goes to player A, 17 to player B, and the remaining 17 to the draw pile. Jacks and queens add 10 to the score. Aces add nine, and each numerical card adds a score equivalent to the...

A golf ball is hit and makes a 45o angle with the horizontal as it leaves the tee. It lands 200 m away. What was the ball’s initial speed? I though i know this well but i don't even know how to set this up

I discussed with my students that if force remains constant and mass decreases then acceleration increases (a=F/m). I also explained that if force remains constant and mass increases, acceleration decreases. I know that there are a number of variables that play into this next situation and I...
