Eventually wouldn't it collapse in on itself and create black hole.
Answer:
2.572 m/s²
Explanation:
Convert the given initial velocity and final velocity rates to m/s:
- 65 km/h → 18.0556 m/s
- 35 km/h → 9.72222 m/s
The motorboat's displacement is 45 m during this time.
We are trying to find the acceleration of the boat.
We have the variables v₀, v, a, and Δx. Find the constant acceleration equation that contains all four of these variables.
Substitute the known values into the equation.
- (9.72222)² = (18.0556)² + 2a(45)
- 94.52156173 = 326.0046914 + 90a
- -231.4831296 = 90a
- a = -2.572
The magnitude of the boat's acceleration is |-2.572| = 2.572 m/s².
Answer:
F=124.03 N
Explanation:
Given data
mass m=5.00 kg
y(t)=(2.80 m/s)t+(0.61m/s³)t³
To find
Force F at t=4.10 s
Solution
As
derivative with respect to time we get
again derivative with respect to time to get acceleration
at t=4.10 s then a(t) is
a=3.66(4.10)
a=15.006 m/s²
Now to use Newton law to find force in y direction
