An object moving with constant acceleration along a horizontal path covers the distance between two points 60 m apart in 6.0 s. Its speed as it passes the second point is 15 m/s. Find (a) the speed at the first point, (b) its acceleration and (c) the distance from the point where the object was at rest to the first point.

Problem 1: In a lunapark, there is an amusement machine simply turning around with 0 = 4[t+30e−0.03 - 30] rad where t is in seconds. If the person loses consciousness at an acceleration level of 10g, a) determine the time t at which this would occur. 4 m 30 m 40 m Conductor a = 2 m/s² 3 m Figure 1 Passenger
The Moon is about 3.8 ✕ 108 m from Earth. Traveling at the speed of light, 3.0 ✕ 108 m/s, how long does it take a laser beam to go from Earth to the Moon and back again (in s)? The same physics was responsible for the noticeable delay in communications signals between lunar astronauts and controllers at the Houston Space Flight Center.
Bob has just finished climbing a sheer cliff above a level beach and wants to figure out how high he climbed. All he has to use is a baseball, a stopwatch, and a friend on the ground below with a long measuring tape. Bob is a pitcher and knows that the fastest he can throw the ball is about ?0=34.1 m/s.v0=34.1 m/s. Bob starts the stopwatch as he throws the ball, with no way to measure the ball's initial trajectory, and watches carefully. The ball rises and then falls, and after ?1=0.910 st1=0.910 s the ball is once again level with Bob. Bob cannot see well enough to time when the ball hits the ground. Bob's friend then measures that the ball hit the ground ?=123 mx=123 m from the base of the cliff. How high above the beach was the ball when it was thrown?

A lidar (laser radar) gun is an alternative to the standard radar gun that uses the Doppler effect to catch speeders. A lidar gun uses an infrared laser and emits a precisely timed series of pulses of infrared electromagnetic waves. The time for each pulse to travel to the speeding vehicle and return to the gun is measured. In one situation a lidar gun is a stationary police car observes a difference of 1.16 x 10 s in round-trip travel times for two pulses that are emitted 0.550 s apart. Assuming that the speeding vehicle is approaching the police car essentially head-on, determine the speed of the vehicle.
