Answer: 2.92 s
Explanation:
Given
Mass of ball is 
The initial velocity of the ball is 
Velocity after the rebound is 
Force during the contact is 
We know, change in momentum is Impulse


Thus, the force is applied for 2.92 s
The correct answer is <span>The car has both potential and kinetic energy, and it is moving at 24.6 m/s.</span>
40 seconds I’m pretty sure sorry if I’m wrong
Answer:
Ur answer is Stationary Front
Explanation:
Stationary Front is when a cold air mass and a warm air mass but are at a standstill the boundary is called Stationary Front.
Force=A×M
10m/s×0.20kg
=2Newton
