Can someone please help me with this problem?
4. The race car travels around the circular track with a speed of 16 m/s. When it reaches point A it increases its speed at a (4) m/s2, where v is in m/s. Determine the magnitudes of the velocity and acceleration of the car when it reaches point B. Also, how much time is required for it to travel from A to B? 200 m Figure: 12 P155
45 25 m/s 1.5 m/s Car A travels along a straight road at a speed of 25 m/s while accelerating at 15 m/s. At this same instant car C is traveling along the straight road with a speed of 30 m/s while decelerating at 3 m/s?.Determine the velocity = 100 m 3 m/s 30° and acceleration of car A relative to car C. 2 m/s 30 m/s 15 m/s
1.) A car starting from rest is travelling with a constant acceleration of 30 m/s2. Find its velocity after 5 seconds. Find its position after 5 seconds. Find the time it would reach 600 m/s Find the distance it has traveled upon reaching a speed of 600 m/s 2.) A particle travels from 100 m/s to 1000 m/s. Find its constant acceleration if this was done in 5 seconds. What is the distance traveled during the 5 seconds interval? Find...
Problem 4 A car travels along a straight road at a speed of 20 m/s, it decelerates uniformly to a stop over a period of 30 seconds; the car then it travels in the opposite of the original direction accelerating uniformly to a speed of 30 m/s in that direction over a period of 15 seconds a) Prepare a scaled time-velocity graph. b) Prepare a scaled time-acceleration graph. c) Prepare a scaled time-distance traveled graph. d) Determine average velocity of...
Car A goes along a curve of 100 m radius at a speed of 10 m/s and increasing at the rate of 5 m/s2 whereas Car B is moving along a straight stretch of road with a velocity of 18.5 m/s and increases at a rate of 2 m/s2. The position of both cars A and B at a particular instant is as shown in Figure Q2(a). Calculate the acceleration of car A relative to car B and their relative...
Car B turns such that its speed is increased by
(at)B =
(0.5et) m/s2, where t is in seconds. If the
car starts from rest when θ=0o, determine the magnitudes
of its velocity and acceleration when t=2 s. Neglect the size of
the car.
A motorist with an expired license tag travels at a constant speed of 11.8 m/s down a street, and a policeman on a motorcycle, taking another 4.26 s to finish his donut, gives chase at an acceleration of 2.81 m/s2. (a) Find the time required to catch the car. (b) Find the distance the trooper travels while overtaking the motorist.
A motorist with an expired license tag travels at a constant speed of 14.4 m/s down a street, and a policeman on a motorcycle, taking another 4.01 s to finish his donut, gives chase at an acceleration of 2.23 m/s2. (a) Find the time required to catch the car. t = s (b) Find the distance the trooper travels while overtaking the motorist. x = m
A racing car travels on a circular track with a radius of 200 m. If the car moves with a constant linear speed of 51.0 m/s, find (a) its angular speed and (b) the magnitude and directions of its acceleration. (a) 0.255 rad/s; (b) 51.0 m/s2 in the direction of tangential velocity (a) 0.255 rad/s; (b) 13.0 m/s2 in the direction of tangential velocity (a) 7.25 rad/s; (b) 13.0 m/s2 in the direction of tangential velocity (a) 0.255 rad/s; (b)...
If the car passes point A with a speed of 20m/s and begins to
increase its speed at a constant rate of at=0.5m/s2, determine the
magnitude of the car’s acceleration when S = 101.68 m and x =
0.
