A 7 kg steel ball strikes a wall with a speed
of 8.77 m/s at an angle of 59.4 with the
normal to the wall. It bounces off with the
same speed and angle

If the ball is in contact with the wall for
0.237 s, what is the magnitude of the average
force exerted on the ball by the wall?
Answer in units of N

do you have the formula they want you to use? I dont want to get it wrong.
is it$$F * \Delta t = m_2 v_2 - m_1 v_1 $$

idk the formula :/

anonymous · Answer

but the mass doesn't change nor the speed

best of luck. ill check back on this thread to see how its done
