True because the speed of a mass can change it's gravitational potential energy in the gravitational field of another massive object.
We don't know the direction of the acceleration, but we
do have enough information to calculate its magnitude:
|acceleration| = (change in speed) / (time for the change)
= (20 m/s) / (3.5 s)
= 5.714... m/s² (rounded(
Answer:
The acceleration of the car is 1.02 m/s².
Explanation:
Given that,
mass = 10 g
Angle = 6°
Suppose we need to find the acceleration of the car.
We need to calculate the tension
Using balance vertical force

Put the value into the formula



We need to calculate the acceleration of the car
Using balance equation


Put the value into the formula


Hence, The acceleration of the car is 1.02 m/s².
Answer:
31.3 m/s
Explanation:
Centripetal acceleration = v² / r where r is the length of the arm of the chair
98 m/s² = v² / r
v² = √(98 m/s² × 10) = 31.3 m/s
