A golf club contacts a golf ball for 0.15s at an angle to the horizontal and the ball strikes the ground a distance away. Initial speed is 25 m/s
Angle of projection is 15 degrees
Calculate time between ball leaving club and when it touches ground
The range of the ball down fairway and average force exerted by club on ball.
Can you direct me I'm not great at deciphering the info I need to put into formulas that's the part that confuses me
Thanks

That is the part that is physics: analyzing and modeling problems.
Break the initial velocity into vertical and horizontal components.
vertical: 25sin15
horizontal: 25cos15
the time in air depends on the vertical.
hf=hi+Vivertical*time4.9t^2
hf=hi=0
solve for time t.
then, horizontal distance=t*horizontalvelocity
finally: average force on ball
force*timeimpact=changemomentum
force*.15s=massball*25
I don't see massof the ball mentioned.
