A juggler throws a bowling pin straight up with an initial speed of 7.4 m/s from an initial height of 3 m. How much time elapses until the bowling pin returns to the same initial height? (Do not round off the final answer)
The world-record time for the 100 m dash is approximately 10 s. Given this, is it reasonable to expect Brady to be able to run fast enough to achieve Brady's leap? What maximum horizontal range could the dolphin achieve?
Can an object have a varying speed if its velocity is constant? Can it have varying velocity if its speed is constant? If yes, give examples in each case.
Can an object have a negative acceleration and be speeding up? If so, describe a possible physical situation and a corresponding coordinate system. If not, explain why not.
As soon as a ball was allowed to fall from rest from height h, a second ball was thrown upwards from the ground in the vertical direction. For two balls to meet at height h / 2, what should the initial velocity of the second ball be?
On a one lane road, a person driving a car at v1 = 54 mi/h suddenly notices a truck 0.65 mi in front of him. That truck is moving in the same direction at v2 = 35 mi/h. In order to avoid a collision, the person has to reduce the speed of his car tov2 during time interval Δt. The smallest magnitude of acceleration required for the car to avoid a collision is a. During this problem, assume the direction of motion of the car is the positive direction. Refer to the ﬁgure. Part (a) Enter an expression, in terms of deﬁned quantities, for the distance, Δx2, traveled by the truck during the time interval Δt. Part (b) Enter an expression for the distance, Δx1, traveled by the car in terms of v1, v2 and a. Part (c) Enter an expression for the acceleration of the car, a, in terms of v1, v2, and Δt.

During this problem, assume the direction of motion of the car is the positive direction. Refer to the ﬁgure. The expression, in terms of deﬁned quantities, for the distance, Δx2, traveled by the truck during the time interval Δt is deltax2= v2 times delta t.

(d) enter an expression for delta x1 in terms of delta x2 and d when the drive just barely avoids collision.
The record distance in the sport of throwing cowpats is 81.1 m.m. This record toss was set by Steve Urner of the United States in 1981 . Assuming the initial launch angle was 45∘45∘ and neglecting air resistance, determine (a) the initial speed of the projectile and (b) the total time the projectile was in flight.
Can the velocity of an object be negative when its acceleration is positive? What about vice versa? If yes, give examples in each case
Most important in an investigation of an airplane crash by the U.S. National Transportation Safety Board is the data stored on the airplane’s flight-data recorder, commonly called the “black box” in spite of its orange coloring and reflective tape.The recorder is engineered to withstand a crash with an average deceleration of magnitude 3450 g during a time interval of 6.49 ms. In such a crash, if the recorder and airplane have zero speed at the end of that time interval, what is their speed at the beginning of the interval?
Consider two friends: Alice on the left and Bob on the right. Theyrun toward each other. Initially the two are 54 m apart.
