Since the ball was not moving before it let Aiden's hand, the formula used to calculate the acceleration is
, where a is acceleration, v is velocity and t is the time. We put them in the formula and get
The acceleration is 490 m/s^2
Answer:
The position for mass is
Explanation:
Let x(t) donate the position of mass at time t,Then x satisfies the differential equation
The general solution is
It follows
thus the position of mass is
Answer:
A) 29.4 m 17.0 m; B) 2 m
Explanation:
If a vector is 34.0 m in length and is directed 60.0° east of north (which means 30.0° over the horizontal), then its coordinates will be:
Horizontal: (34.0 m)cos(30.0°)=29.4 m
Vertical: (34.0 m)sin(30.0°)=17 m
If one person walks 8.0 meters in a straight line and then walks 5.0 meters in another straight line, then the minimum displacement would be to go back over his tracks, displacing himself 8m-5m=3m, while the maximum displacement would be going straight ahead, displacing himself 8m+5m=13m. Any answer outside this interval is impossible (2m).
Answer:
Distance traveled by projectile in horizontal direction will be 4.95 m
Explanation:
We have given horizontal velocity of the projectile v = 9 m/sec
We have to find the distance traveled by projectile in 0.550 sec in horizontal direction.
We know that distance is equal to multiplication of speed and time
So distance traveled in horizontal direction will be equal to
So distance traveled by projectile in horizontal direction will be 4.95 m
