You can find
1) time to hit the ground
2) initial velocity
3) speed when it hits the ground
Equations
Vx = Vxo
x = Vx * t
Vy = Vyo + gt
Vyo = 0
Vy = gt
y = yo - Vyo - gt^2 / 2
=> yo - y = gt^2 / 2
1) time to hit the ground
=> 8.0 = g t^2 / 2 => t^2 = 8.0m * 2 / 9.81 m/s^2 = 1.631 s^2
=> t = √1.631 s^2 = 1.28 s
2) initial velocity
Vxo = x / t = 6.5m / 1.28s = 5.08 m/s
3) speed when it hits the ground
Vy = g*t = 9.81 m/s * 1.28s = 12.56 m/s
V^2 = Vy^2 + Vx^2 = (12.56 m/s)^2 + (5.08 m/s)^2 = 183.56 m^2 / s^2
=> V = √ (183.56 m^2 / s^2) = 13.55 m/s
The acceleration of the dragster is 8.89 m/s².
To find the acceleration, the given values are,
V₀ = 85 m/s
V = 45 m/s
<h3>What is acceleration?</h3>
- Acceleration is a rate of change of velocity with respect to time with respect to direction and speed.
- Acceleration formula can be written as,
`
a = acceleration
v = final velocity
v₀= starting velocity
t = time
- Acceleration is a vector quantity.
- The unit of acceleration is m/s².
Substituting the given values in the formula,
a = (V-Vo)/time
= (45-85m/s)/4.5 s.
a = 8.89m/s².
Thus, the acceleration a of the dragster is 8.89 m/s².
