A small plastic ball is connected to a lightweight cord of length L-1.40 m that is tied to a point P, as shown in the figure. The ball string and point all lie on a frictionless, horizontal table. The ball has a mass m = 0.0100kg, a charge q = +2.10 C and is released from rest when the string makes an arigle θ = 60.0° with a uniform electric field of magnitude E= 350 V/m. Determine the speed (in m/s) of...
A 0.50 kg ball that is tied to theend of a 1.0 m light cord is revolvedin a horizontal plane with the cord making a 30° angle, withthe vertical (See Fig. P7.52.)Figure P7.52(a) Determine the ball's speed. m/s(b) If, instead, the ball is revolved so that its speed is 4.0 m/s,what angle does the cord make with the vertical?°(c) If the cord can withstand a maximum tension of 9.1 N, what is the highest speed at which the ballcan move?...
Please show work, so i can
practice.
A ball is attached to a cord of length L, which is tied to a frame attached to a truck bed as shown in figure (a) below. The ball-truck system is initially traveling to the right at constant speed vi, with the cord vertical. The truck suddenly stops when it undergoes an inelastic collision with a low wall as shown in figure (b), below. The suspended ball swings through an angle 6. figure...
I 2) A uniform solid ball has a mass of 20 g and a radius of 5 cm. It rests on a horizontal surface. A sharp force is applied to the ball in the horizontal direction 9 cm above the surface. The force rises linearly from 0 to a peak value of 40,000 N in 10-* s and then decreases linearly to o in another 10- s. (The moment of inertia for a solid ball ismR?) a) What is the...
in 32 You throw a ball toward a he wall at speed 25.0 m/s and at angle at 40.0° above the horizontal a (Fig. 4-35). The wall is distance d as 22.0 m from the release point of the le ball. (a) How far above the release 38 point does the ball hit the wall? Figure 4-35 Problem 32. What are the (b) horizontal and (c) vertical components of its velocity as it hits the wall? (d) When n, at...
I need to answer how high the ball went?
1. (6 pts) Ball- y O On the figure above, label the positions with the highest speed (A), the lowest speed (B) and the highest velocity (C). (note, there can be more then one of some of these positions) (a) (b) If a ball is thrown straight up at 20 m/sec, how long does it take to get back to your hand?
You throw a ball toward a wall at speed 25.0 m/s and at angleθ
= 40.0 degrees above the horizontal. (Fig. 4-38) The wallis
distance d = 22.0 m from the release point of the ball.(a)
How far above the release point does the ball hit the wall?What are
the (b) horizontal and (c) vertical components of itsvelocity as it
hits the wall? (d) When it hits, has itpassed the highest point on
its trajectory?

A soccer kicker must kick a ball from a point 36 m from the
goal. Half the crowd hopes the ball will clear the crossbar, which
is 3.05 m high. When kicked, the ball leaves the ground with a
speed of 20 m/s at an angle of 53° to the horizontal.
By how much
does the ball clear or fall short of clearing the crossbar?
please answer these two questions correctly
I AT&T 7:01 PM 80%O Question ? A ball...
The 200-g billiard ball is moving with a speed of 1.5 m/s when
it strikes the side of the pool table at A. The coefficient of
restitution between the ball and the side of the table is e = 0.6.
Neglect the size of the ball. (Figure 1)
Part A
Determine the speed of the ball just after striking the table
twice, i.e., at A, then at B.

Part A With what minimum speed must you toss a 200 g ball straight up to hit the 15-m-high roof of the gymnasium if you release the ball 1.5 m above the ground? Solve this problem using energy. Express your answer using two significant figures. (answer v_min = m/s) Part B With what speed does the ball hit the ground? Express your answer using two significant figures. (answer v = m/s)
