As per Newton's 2nd law
we know that
it is product of mass and acceleration
here we know that
also we know that
so from above equation we have
so the force here will be 10020 N
Answer:
The velocity with which the ball strikes the ground = -5.7 m/s
The velocity with which the ball leaves the ground = 4.3 m/s
Explanation:
Seems like there's parts of a couple questions. I'll focus on the tennis ball part which seems to be a full question.
To find the velocity with which the tennis ball hits the ground, we only need to worry about what happens up to that point. We can ignore the rebound for this part. Given:
d = -1.85
a = -9.8
vi = 0
vf = ?
*Keep in mind that the square root gives us two answers, a positve and a negative one. We use the negative one here because the final speed is downwards and the question says down is negative.
To find the velocity with which the ball leaves the ground, we only need to worry about what happens after that point. We can ignore the drop for this part. Given:
d = 0.947
a = -9.8
vf = 0
vi = ?
*Here we use the positive speed after the square root because we know the ball is going up, which the question designates as the positive direction.
While returning back in opposite direction driver see that rain drops are falling vertically down
so horizontal speed of rain with respect to driver must be Zero
while moving towards the north direction driver see that the rain drops makes an angle 38 degree with the vertical
so the speed of rain is
also the angle is given as
