You throw a baseball at an angle of 30.0∘∘ above the horizontal. It reaches the highest point of its trajectory 1.05 ss later. A

garri49 [273]

Answer:

The speed with which the baseball leaves the hand = 20.58 m/s

Explanation:

The time take to reach highest height during a projectile's flight is given by

t = (u sin θ)/g

u = initial velocity of the baseball = ?

θ = angle of throw above the horizontal

g = acceleration due to gravity = 9.8 m/s²

1.05 = (u sin 30)/9.8

u = (1.05 × 9.8)/0.5

u = 20.58 m/s

Tanya [424]

Answer:

Q1: c

Q2: a

Explanation:

you can tell the factors by looking at the formulas for kinetic and potential energy

for question 1 look at the formula for kinetic energy

$KE=\frac{1}{2} mv^{2}$

the variables needed in order to calculate an object's kinetic energy are mass and velocity.

hence, when mass and velocity changes, kinetic energy changes, showing that mass and velocity are the factors affecting kinetic energy

same thing for the second question

$PE = mgh$

as g (acceleration due to gravity) is considered constant (10 $m/s^{2}$ ) it will not be considered as a factor

and thus, the factors affecting potential energy are mass and height
