Let’s say you have a spring. You press on the spring with your finger. The spring goes down. This is the action force. Then, the spring goes back up after you take your finger off of it. This is known as the reaction force.

The pitchers mound in baseball is 85 meters from home plate . If it takes 4.1 seconds for a pitch to reach the plate , how fast
adoni [48]

Answer: 20.73m/s

Explanation:

The question simply wants us to calculate the speed of the pitch. The speed will be calculated as:

= Distance/Time

where,

Distance = 85 meters

Time = 4.1 seconds

Speed = Distance/Time

Speed = 85/4.1

Speed = 20.73m/s

Therefore, the speed of the pitch is 20.73m/s.

1) A football player kicks a ball at an angle of 30 and gives it a velocity of 15m/s.
mote1985 [20]

Answer:

A) 1.53s

B) 19.8m

C) 2.869m

Explanation:

A) The time of flight for a projectile can be calculated using the formula:

t = 2μsinθ/g

Where; u = velocity

θ = angle

g = acceleration due to gravity (9.8m/s^2)

t = 2 × 15 × sin 30°/9.8

t = 30sin30°/9.8

t = 30 × 0.5/9.8

t = 15/9.8

t = 1.53s

B) The horizontal range (distance) for a projectile can be calculated using the formula:

Range = u²sin2θ/ g

Range = 15² sin 2 × 30 / 9.8

Range = 225 sin 60/9.8

Range = 225 × 0.8660/9.8

Range = 194.855/9.8

Range = 19.8m

C) The maximum height for a projectile can be calculated using the formula:

h = u²sin²θ/2g

h = 15² (sin 30)² / 2 × 9.8

h = 225 × 0.25 / 19.6

h = 56.25/19.6

h = 2.869m
