Answer:
Electric field on proton
Explanation:
Given that
We know that
Charge on proton
We know that
Force = Electric field x Charge
F= E x q
Electric field on proton
The answer given by E2020 is
"The padding around the goal post increases the time of the collision between the player and the post, which decreases the force exerted to bring the player to a stop"
Answer:
Velocity of the ping pong ball must be = V2= 6,035.34m/s
Explanation:
M1= momentum of the bowling ball
m1 = mass of the bowling ball= 5.8kg
v1= velocity of the bowling ball= 1.59m/s
M2= momentum of the ping pong ball
m2= mass of the ping pong ball= 1.528 g/1000= 0.001528kg
v2= velocity of the ping pong ball
Momentum of the bowling ball= M1= m1v1= 5.8* 1.59= 9.222 kg-m/s
Momentum of the ping pong ball = M2= M1= m2v2
= 0.001528 *v2= 9.222
v2= 9.222/0.001528= 6,035.34 m/s
