Answer:
Change in momentum,
Explanation:
It is given that,
Mass of the basketball, m = 601 g = 0.601 kg
The basketball makes an angle of 29 degrees to the vertical, it hits the floor with a speed, v = 6 m/s
It bounces up with the same speed, again moving to the right at an angle of 29 degree to the vertical. We need to find the change in momentum. It is given by :
So, the change in momentum of the basketball is 6.3 kg-m/s. Hence, this is the required solution.
Answer:
The initial velocity of the gymnast is 8.5 m/s.
Explanation:
We can use the kinematic equation
to figure out the initial velocity of the gymnast.
Now, when the gymnast reaches the maximum height, the distance he has traveled is , and his velocity is zero; therefore .
Thus, we have
Answer:
Explanation:
1.) electric source of light
2.) measurement of length
hope this helped :) x
Part 1. F= m*a
M=12kg
A= 3 m/s^2
So F = 12kg * 3 m/s^2 which means
F=36 Newton’s
Part 2. F=12000N
M= F/A
A=4 m/s^2
So M= 12000N / 4 m/s^2
Which means M=3000 kg
Answer:
because the faster u gp it will take the car to slow down because of accleration.
Explanation:
because of acceleration it makes it harder for the car to slow down
