Answer:
Vf = 68.67[m/s]
Explanation:
To solve this problem we must use the following kinematics equation:
where:
Vf = final velocity [m/s]
Vi = initial velocity = 0
g = gravity = - 9.81 [m/s2]
t = time = 7 [s]
Vf = 0 - (-9.81*7)
Vf = 68.67[m/s]
Answer:
Explanation:
As we know that initial velocity of the cart is given as
initial position is given as
acceleration of the cart is given as
now position of the cart after t= 0.40 s is given as

1.) Use the formula to solve -
1/f = 1/do + 1/di; Where f = focal length; 1/do + 1/di
1/f = 1/do + di
1/8 = 1/25 + 1/?
.125 = .04 + 1/di
.125 -.04 = 1/di (transferred .04 to the left side of the equation)
.085/1 = 1/di
.085di/.085 = 1/.085 (multiplied both sides by di and divided both sides by .085)
di = 11.76 or 12
2.) Therefore, 12 cm is the distance from the image to the mirror
