A 3.30-kg steel ball strikes a massive wall at 10.0 m/s at an angle of θ = 60.0° with the plane of the wall. It bounces off the wall with the same speed and angle (see the figure below). If the ball is in contact with the wall for 0.204 s, what is the average force exerted by the wall on the ball? find magnitude?
for magnitude i got -280.2 N which is incorrect.
i used the equation
F = −2mv sin(θ)/∆t
so can anyone help me!!!!!please

What subject is "p"? Phys Ed, Physics, Playground?
I'm a current physics student with a similar problem. However, this equation worked for me, I just removed the negative from the front.
