Mademuasel [1]3 years ago
3 0

Answer:

100 m.

Explanation:

At first the car was stationary, so its inicial velocity is zero. Considering its inicial position 0 m and using the Equation of motion for the position:

X(t) = Xo + vo.t +at^{2}/2 , vo=0, Xo=0, a=2m/s^{2}

X(10) = (2 x 10^{2})/2 = 100 m.

A boy throws a baseball onto a roof and it rolls back down and off the roof with a speed of 3.75 m/s. If the roof is pitched at
dalvyx [7]

Answer:

a) t = 0.528 s

b) D = 1.62 m

Explanation:

given,

speed of the baseball = 3.75 m/s

angle made with the horizontal = 35°

height of the roof edge = 2.5 m

using equation of motion

s = ut +\dfrac{1}{2}gt^2

2.5 = vsin\theta \ t +\dfrac{1}{2}gt^2

2.5 = 3.75\ sin35^0 \ t +\dfrac{1}{2}\times 9.8 t^2

4.9 t² + 2.15 t - 2.5 = 0

on solving the above equation

t = 0.528 s

b) D = v cos θ × t

D = 3.75 × cos 35° ×0.528

D = 1.62 m

In order to start an object moving, you must first overcome the force of _________ friction.
navik [9.2K]
It would be static friction which is what you have to overcome when an object is not in motion. When you move an object friction works against it like gravity and air resistance. I hope this helps!
