Question

you throw a ball into the air with an initial speed of 10 m/s at an angle of 60 ∘ above the horizontal. the ball returns to the level from which it was thrown in the time t .

Answer 1

To find the impulse delivered by the wall, calculate the change in momentum of the ball.

Step-by-step explanation:

To find the impulse delivered by the wall, we need to calculate the change in momentum of the ball. The initial momentum of the ball is given by the product of its mass and initial velocity, which is m * 10 m/s.

When the ball bounces off the wall, its velocity changes direction but its speed remains the same. So, the final momentum of the ball is also m * 10 m/s. The change in momentum, or the impulse delivered by the wall, is equal to the final momentum minus the initial momentum.
