In t-ball, young players use a bat to hit a stationary ball off a stand. the 140 g ball has about the same mass as a baseball, but it is larger and softer. in one hit, the ball leaves the bat at 12m/s after being in contact with the bat for 2.0ms . assume constant acceleration during the hit.
a. what is the acceleration of the ball? express your answer to two significant figures and include the appropriate units. a =
b. what is the net force on the ball during the hit?
express your answer to two significant figures and include the appropriate units.
f =

Explanation:

It is given that,

Mass of the ball, m = 140 g = 0.14 kg

Initial speed of the ball, u = 0

Final speed of the ball, v = 12 m/s

Time of contact,

(a) Let a is the acceleration of the ball. It is equal to the rate of change of velocity. It is given by :

(b) Let F is the net force on the ball during the hit. It is equal to the product of mass and acceleration. It is given by :

F = 840 N

Hence, this is the required solution.

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

the total distance traveled by the car is

30km + 49km = 79 km .
