Answer:
Vf = 4.77 m/s
Explanation:
During the downward motion we can easily find the final velocity or the velocity with which the ball hits the ground, by using third equation of motion. The third equation of motion is given as follows:
2gh = Vf² - Vi²
where,
g = acceleration due to gravity = 9.8 m/s²
h = height = 1.16 m
Vf = Final Velocity of Ball = ?
Vi = Initial Velocity of Ball = 0 m/s (Since, ball was initially at rest)
Therefore, using these values in the equation, we get:
(2)(9.8 m/s²)(1.16 m) = Vf² - (0 m/s)²
Vf = √(22.736 m²/s²)
<u>Vf = 4.77 m/s</u>
Answer:
d = 1600 m
Explanation:
If car start from rest and accelerates uniformly then the displacement of the car is given as

now we know

now if the same car will accelerate from rest for four times of the previous time interval
then we will have


so the distance will be 16 times more

Answer:
The magnitude of the motorcycle's acceleration is 5.20 m/s².
Explanation:
Given that,
Mass of motorcycle = 296 kg
Angle = 26.2°
Force on motorcycle= 3106 N
Force = 286 N
We need to calculate the magnitude of the motorcycle's acceleration
The net force acting on the motorcycle
Using newton's second law


Put the value into the formula



Hence, The magnitude of the motorcycle's acceleration is 5.20 m/s².
