AI Thread Summary
To determine how long the clubhead is in contact with the golf ball, the law of impulses can be applied, which states that the change in momentum (Δp) equals the average force (F) multiplied by the time of contact (Δt). The momentum change can be calculated using the mass of the golf ball (0.05 kg) and its initial speed (80 m/s). The average force exerted on the ball is given as 6500 N. By rearranging the formula to solve for Δt, the time of contact can be determined. This approach effectively utilizes the relationship between force, momentum, and time.

HELP! i can't think of the formula!

Homework Statement



A 0,05kg golf ball is driven from the tee at a speed of 80m/s. if the average accelerating force on the ball is 6500N, determine how long the clubhead is in contact with the ball.

Homework Equations





The Attempt at a Solution



I have sat staring at this question for awhile. could somebody please help me out so i can substitute...?
 
Physics news on Phys.org


Have you heard of the law of Impulses?
It states that: \Delta{\vec{p}} = \overline{\vec{F}}\Delta{t}
Try it.
Where dP is the change in momentum, and F is the average force...

Thank you

What would Δp⃗ be?

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
